Who is Rare Yool in My Singing Monsters?

How to Breed a Rare Yool?

The Rare Yool is the seasonal variant of the regular Yool monster. It has a white fur coat accented with red and green, as well as red antlers and hooves. The Rare Yool also sports jingle bells around its neck that jingle when it dances.

Rare Yool was added to My Singing Monsters in version 2.0.3 released on December 2, 2016. It is classified as a rare seasonal monster that celebrates the in-game Festival of Yay holiday season.


The Rare Yool sings the same vocal parts as the regular Yool, contributing its high-pitched “yoolie-yay” phrases to Cold Island’s harmony.

How to Breed a Rare Yool?

Breeding a Rare Yool requires precise timing, as it is only available for limited windows of time. It can only be bred during the Festival of Yay season, its Out-of-Season weekend, and the Anniversary Month Celebration.

On Cold Island, the breeding combination is:

Rare Yool Breeding Combination 1

  • Thumpies + Congle

On Seasonal Shanty, breed a regular Yool with any monster that has a seasonal element. The best combinations are:

Rare Yool Breeding Combination 2

  • Yool + Monculus
  • Yool + Spurrit
  • Yool + Gobbleygourd
  • Yool + Clavavera
  • Yool + Viveine
  • Yool + Jam Boree
  • Yool + Carillong
  • Yool + Whiz-bang
  • Yool + Ffidyll
  • Yool + Boo’qwurm

The best combinations are Yool + Monculus, Yool + Spurrit, and Yool + Gobbleygourd because they have the shortest wait times if you don’t get a Rare Yool.

Once you have bred one Rare Yool, you can also breed it with a regular Yool to increase your chances of breeding another Rare Yool.

Breeding any monster that has a seasonal element with a regular Yool on Seasonal Shanty has a chance of resulting in a Rare Yool instead. However, the combinations listed above are optimal.
