| “ | Towards the end of the year, the plump and pleasant Yool schedules a relaxing sojourn on Cold Island. Its arrival is heralded by the jingle bells dangling from its antlers, and the booming resonance of its voice. Just being near a Yool produces feelings of peace and joy, so the other Monsters always try and convince it to stay the whole year round. | ” |

Description[]
Yool is a Seasonal Monster that celebrates the Festival of Yay season and is found on Cold Island, Seasonal Shanty, The Colossingum, and Gold Island. It was added on December 6th, 2012 during Version 1.1.0. As a Seasonal Monster, it is only available at certain times. It is best obtained by breeding Thumpies and Congle. By default, its breeding time is 1 day and 12 hours long. Although Yool does not have good Coin production when collecting once per day, when collecting multiple times it can rival other Monsters such as Ethereals or Quad-Elements.
Yool can be teleported to Seasonal Shanty once fed to level 15. Yool has a decent Coin production compared to other Monsters on Seasonal Shanty. The Goal for placing a Yool on Seasonal Shanty rewards the player with 3

VSTs[]
- Main article: VSTs
Virtual Studio Technology is an audio plugin software that has libraries of sound effects and synthesized instruments. Within these libraries are SoundFonts, which are the individual effects and instruments themselves. The Monster-Handlers utilize several VSTs to create the sounds of instrumental and sometimes vocal Monsters.

Breeding[]
On Cold Island, Yool can only be bred for a limited time during the Festival of Yay event or Out of Season promotions:
+ Thumpies and Congle
- Can result in a Rare Thumpies, Rare Congle, Rare Mammott, or Rare Tweedle if any are available
On Seasonal Shanty, the only way to get a Yool without already having another Yool on the island is through teleporting.
Any breeding combinations containing a Yool may fail, and give one of the parents as a result. However, breeding a Yool with an Aux. Seasonal is preferable, as it has a higher chance of getting another Yool than that of getting an Aux.:
- + Yool and Gobbleygourd
- + Yool and Clavavera
- + Yool and Viveine
- + Yool and Jam Boree
- + Yool and Carillong
- + Yool and Whiz-bang
- + Yool and Monculus
- + Yool and Ffidyll
- + Yool and Boo'qwurm
- + Yool and Spurrit
Out of these, Yool + Monculus is the best combination, as it has the lowest waiting time in case of not resulting in another Yool. Yool + Spurrit and Yool + Gobbleygourd are also good choices.
The Rare variant of any breeding Monster can be used instead of the Common variant.
However, on Seasonal Shanty, the best way of getting a duplicate Yool is by breeding a Common Yool with its Rare variant, with a 100% chance of getting it if the Rare variant is not available:
- + Yool and Rare Yool
On September 12th, 2014, the breeding combination for Yool was changed. The old breeding combination for Yool (Deedge and the Thumpies) was one of the combinations for Grumpyre, but since they both had the same breeding time, it was impossible to distinguish the two Monsters, as both of their speed-up times are 36 hours. The breeding combination change was made to eliminate this potential confusion.
Availability[]
- For a list of when this Monster has been available, see: Breeding Availability
Yool, like all Seasonals are only available during their own season, a weekend Out-of-Season event (6 months apart) and the Anniversary Month Celebration. It is also available to breed at any time on Seasonal Shanty.
NOTE: Yool can only be bred or purchased during the available dates. Any Yools on Cold Island or The Colossingum that are obtained during that time will stay unless they are sold. However, as stated before, Yool can be bought or bred on Seasonal Shanty at any time, though it is discounted when it is available on other islands. Yool is also obtainable via weekly Scratch Tickets on Cold Island or its Mirror Island. Additionally, Yool can be placed on Gold Island at any time once it is level 15 on Cold Island or its Mirror Island.

Egg Consumption[]
- Main article: Zapping
While trying to breed other Monsters (particularly Monsters with a very low chance of breeding), the following Celestials can be used to "dispose of" Yool eggs immediately, instead of putting them into a Nursery and having that Nursery not be available. Note that doing this for Rare and Epic Wublins will cause the Wublin to stop producing currency and the eggs will not expire.
 Yool |
|
Note that Monster eggs can only be "disposed of" before awakening Celestials; afterwards those Monsters will not accept any eggs. Also note that Monsters to which you have already disposed the number of Yool eggs that it accepts, will no longer be available as a "recycle bin" for such eggs. Also note that Seasonal Monsters, like Yool, cannot be zapped from Seasonal Shanty.

Notes[]
- Yool's name is from the ancient pagan mid-winter festival, Yule, which was later absorbed into Christmas. Yule is short for Yuletide.
- Unlike most Monsters, Yool only likes two Decorations (on Cold Island), the Crumpler Tree and the Piney Tree. The same goes for Shugabass.
- Yool made an unofficial appearance in the Market during the Easter 2013 celebration, where it was available for purchase but without confirmation of successful breeding attempts.
- Yool was the first Seasonal to be available on The Colossingum. It was also the first Seasonal to have an Epic variant.
- Until Ffidyll was released and added the new verse, Yool used to play through the entire song on Seasonal Shanty.
- Like deer, Yool typically sheds its antlers between January and March, which is why it is not really seen that often around that time because it is very self-conscious about its appearance.
- Yool was seen in an announcement for Bonus Items.
- The amount of beats Yool sings for doubles with each Island:
- Yool sings for 32 beats in total on Cold Island.
- Yool sings for 64 beats in total on Gold Island.
- Yool sings for 128 beats in total on Seasonal Shanty, excluding when Yool only plays the sleigh bells.
