Yool

"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.

This monster, like all Seasonal monsters, cannot breed."

Description
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.

Song
Audio sample:

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.

Breeding
The Yool Monster can only be bred for a limited time during the Christmas season, and occasionally out of season (see the Notes section below for specific dates). There is one possible combination:


 * Thumpies.png + Congle.png Thumpies and Congle

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.


 * In 2013, the breeding began on December 10th and ended on January 6th, 2014.
 * For Vita players, breeding and purchase availability extends from December 1st to December 31st every year, based on the date set on the system.
 * In 2014, breeding began on December 3rd and ended on January 5th, 2015.
 * In 2015, breeding began on TBA data and ended on TBA date.
 * For 2016, breeding began on December 2nd and will end sometime in January.
 * In 2017, an out of season promotion began 6/16/17. Both Yool and Rare Yool were available.
 * In December 2017, breeding began on December 6th and ended on TBA.

NOTE: can only be bred or purchased during the dates listed. Any s on Cold Island that are obtained during that time will stay unless they are sold.

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, as well as the maximum coins earned.

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:
