"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 him to stay the whole year round ."

The Yool is a stout bearded monster whose upper parts are covered in white fur.
Like many species of real life reindeers, Yools are antler-bearing, have hooves as feet, and brown hair covering their legs. Unlike a reindeer, however, the monsters are bipedal, have elf-like ears and candy-cane-patterned arms, with red and white stripes. The central part of the body of a Yool is green, and has snowflake-like patterns in it.
Furthermore, all Yools have sleigh bells on their antlers, that are used by the monsters to produce their songs.
The Yool sings "Ho Ho Ho Ho" in a resonating baritone voice, as Santa Claus is supposed to do, and also shakes its head quickly to jingle the bells on its antlers.
On September 12th, 2014 the breeding combination was changed. The old breeding combination for Yool (Deedge and Thumpies) was one of the combinations for Grumpyre; since they both had the same breeding time, you would not know which one you would get if the speed-up time was 36 hours. Presumably the breeding combination change was made to eliminate this potential confusion.
NOTE: Yool can only be bred or purchased during the dates listed. Any Yools on Cold Island that are obtained during that time will stay unless they are sold.
Earning rate is in coins per minute.
|Level||0% Happiness||25% Happiness||50% Happiness||75% Happiness||100% Happiness|
Each monster has a limit to how much income it can hold at a time. Increasing the monster's level increases the limit.
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, as well as the maximum coins earned.
|Level||Food Per Feeding||Total Food Needed Per Level|
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%).

The Yool has a variety of translations in the game.
