Shellbeat

"Shellbeats are naturally shy and like to keep hidden away in their shells. When they are woken up by their neighbor's loud singing they tend to loosen up, come out of their shell, and play along as best they can with their aquatic drum set. Shellbeats have gotten pretty good at playing lately."

Description
The Shellbeat is a purple humanoid creature with a snail-like shell on its back. Its tail looks like a squid's tentacle: long, with a pad of suckers on its end. Instead of visible ears, it has small fins. It sits on a light-cyan stool in front of a drum kit consisting of a snare drum and two sets of cymbals, which it plays almost continually. It also hits its shell with its tail, using its shell as a bass drum.

This monster is rarely idle, but when it is, it sways back and forth a bit, and keeps the rhythm by stepping lightly with alternating feet.

Song
Audio sample:

The Shellbeat's contribution to an island's song is a collection of mid-to-high pitch percussion sounds. In addition to its drumset and cymbals, the Shellbeat also uses its own shell as a drum. It plays on the drumset using the sticks in its hand while playing its shell with its tail. Its shell plays the role of producing the bass drum of a drumset.

Breeding
The Shellbeat can be bred using monsters that combine to provide all the elements Plant, Air, Water and Earth without repeating any.

The following pairs of 2-element monsters can be used to breed a Shellbeat:
 * Dandidoo.png + Fwog.png Dandidoo and Fwog
 * Cybop.png + Oaktopus.png Cybop and Oaktopus
 * Quibble.png + Shrubb.png Quibble and Shrubb

However, the combination of a 3-element with 1-element monster has a higher rate of success: The last combination is best, since in case of failure, the Noggin takes much less time to hatch than either Tweedle or Potbelly, and you can try again quickly. Next-best is the combination with the Toe Jammer.

Earning Rate and Maximum Income
Earning rate is in coins per hour and depends on Happiness % (Likes increase Happiness), also each monster has a limit to how much income it can hold at a time. Increasing the monster's level increases the limit.

Feeding Monsters
Each monster needs to be fed four times before it reaches the next level. Increasing the monster's level increases the coins earned per minute. The food per level is the same for all four element monsters and can be found in this article.

Likes
Every monster has different things that they like. For every unique object that they like that's placed near the monster, the monster's happiness will increase by 25% (in other words, placing two of the same liked item near a monster will still only increase happiness by 25%).
 * Noggin
 * Puffle Tree
 * Yum Yum Tree
 * Dragon Tower

Strategy
Some items to take into consideration when designing your island by strategy are number of beds for the monster, rate of income per bed, max income per bed, and time for max income to be reached. The income below is for level 15:

Name Origin
is a compound word of shell and beat, because of the monster's mollusk-like shell and the fact it plays drums during its active periods in-game.

Rare Version
Main Article: Rare Monsters

Rares are special versions of monsters that are only available to buy and breed on weekends. Each weekend a different rare is available to buy or breed. The breeding combination is the same as a regular monster, but the breeding time is longer, the "likes" are different, and the earning rates are higher. They are not yet available in the Windows version of the game.

Find out more about the rare version of the on the Rare  page.
