"The game-changing Tribal Island is here! Just as the last of the Rare monsters was revealed, this extraordinary new realm sprang into existence and ignited a new challenge for novice and seasoned players alike. It's up to you to form a Tribe with your Friends and keep your monster well-fed to raise your Tribal Level, earn Starpower, and redeem Tribal Rewards. You may even unlock "an ancient secret of the monster world!"

About
"Congratulations!

You are now a member of this tribe. Your monster has been placed on the island and you can start feeding it to earn Tribal rewards and Starpower!"

- Notification upon being selected as part of a tribe and arriving at Tribal Island.

Tribal Island was introduced on August 6, 2015, as part of update 1.3.5.

This Island is a collaborative effort between the player and up to 29 of their friends, who form a Tribe. Each friend can contribute one Monster (a "natural" single, double, triple, or quad-element type) to the Tribe's harmony. As the monsters of the Tribe are fed to higher levels, the Tribe as a whole reaches weekly Goals and is rewarded at the end of the week.

It is available for free when the map becomes available at Level 10.

Indigenous Monsters
Similar to Gold Island, the Monsters of Tribal Island are of all elements, but only natural monsters are on Tribal Island. Additionally, every member of a tribe must contribute one natural monster to the island. Multiple monsters of the same species can be placed, meaning that not every monster has to be unique.

Rocks and Trees

 * Main Article: Obstacles

There are no rocks and trees to clear on Tribal Island.

Castle Upgrades
Like Wublin Island, Tribal Island does not have a castle. Instead, Tribal Island has a limited amount of spaces for people to join a tribe (30 spaces).

History
A graphic from the in-game News provides a brief history of Tribal Island in monster script. Translated, it reads:

"At one point in history, few could have foreseen the formation of Tribal Island. After all, the Colossals and their island hosts were fated to go their separate ways, never to rejoin... Were they not? The advent of Tribal Island represents the fulfillment of a prophesy from primitive times, in which greater bonds than ever before will be forged between caretakers of the monster realm. And harmony will once more be achieved."

Since the Islands that the Monsters sing on are considered the Colossals, Kayna may be the caretaker of Tribal Island.

Joining an Island
To begin, select the Tribal Island from the island map. After that, press the "Tribal" button. The Tribal menu contains three tabs: "Tribes", "My Tribe" and "Top Tribes". On the "Tribes" tab, the player can see information about their friends' tribes, visit them, request to join one, or accept an invitation to join one. Alternatively, they can use the Tribal menu to create a new Tribal Island and invite others to it.

A maximum of thirty players can occupy a single Tribal Island. Since there are thirty different natural monsters, any duplicated monster will make it impossible to get the complete choir without replacing one of the duplicates.

The player can only be a part of one Tribe at a time, and they must leave a Tribe before they can join another. Be aware that whenever someone leaves and joins a different Tribal Island, their monster's level is reset to 1.

Each player chooses one (and only one) of the natural monsters for the island. They can only choose from the natural monsters that live on one of their own islands. (For instance, a player can't choose a Quarrister if they haven't bred one on Earth Island yet.) That monster is then fed to higher levels using food, coins, or shards. Monsters on Tribal Island can be fed above Level 15; there does not appear to be a maximum level, although monsters do not grow any larger after Level 15.

Goals
Each Tribal Island has its own Goals that can be achieved in return for diamonds. When a Tribe member feeds their monster to a higher level, the overall level of the Island increases as well. Rewards are distributed among every member of the Island at the end of the week.

Goals are achieved when the Island as a whole reaches Level 30, 50, 100, 150, 300, 450, 600, 750, 1000, and 1500. (Note that if a Tribe has the maximum of thirty monsters, it reaches Level 30 automatically, while Level 1500 is possible if each monster is fed up to Level 50.)

When the Island reaches Level 100, Kayna is released from the amber crystal in the center of the Island and joins the harmony of Tribal island.

At the end of each week, all Tribal Island monsters are reset to Level 1 and the Tribal Island goals are reset.

Feeding
Monsters can be fed with shards, coins, or food. The cost for each feeding is determined by the following formulas:
 * FeedFoodAtLevel(X) = 250 * X * (X + 4)
 * FeedCoinsAtLevel(X) = 10 * FeedFoodAtLevel(X)
 * FeedShardsAtLevel(X) = Floor(FeedFoodAtLevel(X) / 1000)
 * Level Shard Step (L) = L+(L/2)² (-1/4 if odd Level)
 * Shards To Next Level (L) = L² + 4*L (-1 if odd Level)
 * Shards To Level (L) = L³/3 + 3*L²/2 - 7*L/3 (+1/2 if odd Level)

Leveling Up
Shards are the most cost-effective feeding method for levelling up monsters.

Observations:
 * Raising a monster from level n to level n+1 costs 1000*n*(n+4) in food or ten times as many coins.
 * If leveling with coins, the cost to reach level 27 (76,050,000) is higher than buying a Wubbox (at regular price).
 * The best shard to diamond ratio is reached when all 30 island players level their monsters to 50 with shards. Each one would spend 45300 shards and get 20 diamonds in return, a 2265 shard per diamond ratio.
 * The Tribal Level is the sum of all of the monsters' levels. Suppose if all 30 members joined a tribe and had their monsters leveled up to at least Level 4, the Kayna would be unlocked as the Tribal Level would be 120 (the Kayna is unlocked at Tribal Level 100).

Starpower
Starpower is a separate score for each individual player, but it is earned by participating in Tribal Islands. At the end of the week--at the same time as Rewards are distributed for reaching Tribal Goals--every Tribal Island member's Starpower score will increase. The amount of Starpower awarded is calculated based on individual contributions, and increases the more members there are in a Tribe, unlike the diamond rewards which are based solely on the Tribal Island level. Each player earns 5 starpower per individual level contributed, plus a base value common to all tribal members. The formula for the common base value is currently unknown, but for a 30 member tribe, it seems to be equal to the tribal island level plus approximately 250-300 additional starpower.

An individual player's Starpower accumulates continuously from week to week and does not reset when leaving a Tribal Island or joining another. However, staying in the same tribe for a high number of consecutive weeks will make the amount of Starpower you earn higher.

Starpower can be used to make purchases in the StarShop, where players can purchase Rare Monsters and exclusive decorations anytime.

Strategy
Monsters do not earn Currency on Tribal Island. However, players do earn diamonds at the end of the week if the Tribe as a whole achieves certain Goals.

If the player decides to join a tribe, it's up to the Tribe Chief to accept their request. They can improve their chances if they follow these guidelines:
 * 1) Pick a monster not yet in the tribe. Many people would like to hear the whole song and that can't happen if some monsters are missing.
 * 2) After sending a request to join a Tribe, check back frequently to see if the Tribe Chief has accepted it. Popular tribes have many requests to join. If the request is not accepted for several days, cancel it and try a different tribe.
 * 3) Contribute to the tribe by feeding the monster weekly. Don't give the chief a reason to remove it from the tribe.

To get higher amounts of diamonds and Starpower from your Tribal Island:
 * 1) Join a tribe with minimum monster level set 5-10 levels below your maximum capabilities. When tribe members feed their monsters to similar levels, everyone gets the best reward. See Tribe Contacts for some tribes.
 * 2) Invite friends to join who you believe will make a positive contribution to the tribe. If you are a general member, you will only be able to send an invitation if your tribe has 29 or fewer members. All new members must be approved by the chief. By leaving a tribe at 29, a chief can allow current members to refer potential new members them. Good members that level up equals higher earnings for all.
 * 3) Shards are the only reasonable way to level up the monster to a high level. Populate the Ethereal Island soon with as many single-element monsters as possible.
 * 4) A full Ethereal Island with level 15 monsters will allow the player to level-up on Tribal Island to 100 or more in a week (you can earn more than 350,000 if you collect shards 3 times a day).

If you ignore the Starpower, the Tribal Island is a way to convert to. Assuming that all tribe members are evenly using shards to level their monsters, there is a point where it is no longer cost effective to keep leveling up since 30,000 can be traded for 1 in the market. Using this fact, the following table shows what individual levels need to be reached to meet tribal goals. Blank spaces in the table mean that it would cost more shards than it is worth to reach the next goal. For example, in a one-member tribe, it takes 35,020 shards to go from level 30 to level 50 to gain a 1 diamond reward, which is more than the 30,000 shards needed to buy a diamond in the market.

(Note that the higher levels are projected based on patterns found in the "leveling up" table.)

Music
Despite not having a released song for its own song, the tempo and its key signature sound quite different. It plays at 120 beats per minute and at mostly Eb Major.

The song starts with an unpitched percussion instrumental with Shellbeat, Congle, Scups, Shrubb, Clamble,Deedge, and Noggin. Before the fourth bar, the PomPom and Congle sing "Come on let's go!". The PomPom and Congle sing with the Tweedle, accompanying its singing with Potbelly, Pummel, Riff, and Quibble. Later on, the Mammott sings the melody, being primarily accompanied by Oaktopus, Fwog, Bowgart, Drumpler, Pango and Toe Jammer. The Furcorn kicks in with the melody, followed by being accompanied by Entbrat, Maw, and the Thumpies. Kayna then sings the melody, highlighting the climax of the song and being accompanied by Reedling, Spunge, T-Rox, and Dandidoo. This is followed by a PomPom and Congle singing "Come on let's go!" and the Tweedle and Furcorn to sing a simultaneous melody, being accompanied by all other monsters of which they were accompanied with. Following this is a melody of a Cybop and Quarrister, accompanied by a Quibble and T-Rox. The PomPom and Congle sing their lyrics, letting the T-Rox stop playing and lead to a less percussion-dominant ending.

Teasers

 * On July 28th, BBB posted another vine with a woman singing similar to Maw, and confirmed that an announcement will be arriving "later this week".


 * Also on July 28th, a post that included a secret message between 2 Tweedles appeared. It said, "Hey! The monster handlers are working on something. Tell everyone." The other Tweedle responded, "OK! I'll tell them!" The game servers then went into maintenance for several hours.
 * On July 31, BBB posted a trailer for Tribal Island on Youtube, Facebook, and Twitter that showed the Kayna singing.
