Here is the breeding challenge for April, 2018 and the rules for qualification:

Challenge: Breed a cheetah blend Mossm where color 1 is pink and color 2 is rainbow. The prize for completing this challenge is a new bubble Mossm (pink-longfur-rainbow-longfur-bubblebooti).

Secondary Challenge: Breed the challenge Mossm above with Dumbo ears. The prize for completing the secondary challenge is the new butterfly ear power-up.

1. Colors must be in the correct order, if you do not know how to tell please read this document: http://mossms.com/content/traits/
   
2. You must post the URL of your Mossm in the forum thread for this month’s challenge.
   
3. You can only win once.
   
4. If you win the Secondary Challenge you do not get an extra prize Mossm.
   
5. You must breed the Mossm yourself.
   
6. The Mossm must be created during the challenge period.
   
7. You must still own the Mossm at the end of the challenge. If you don’t want to feed it, put it in a cryo-pod until the challenge is over! If you don’t own it I won’t be able to tell if you completed the challenge and you won’t get your reward.
   
8. The challenge begins at the time of this posting and ends on the 15th day of May, 2018.
   
9. Prizes will be delivered the day after the challenge is over.
   

If you mate a Romantic BubbleBath to an Elemental Comedian on Catania would you have a snowballs chance in hell with out a rainbow power up?

Yes, it is entirely possible!

We have released our new automated system for completing your breeding challenges so there is no need to post your URLS here any more. If you didn't see the news post about it, you can learn how it works here:

Breeding challenges will now appear in your control panel and the item for scanning them is available in the TEQ section of the item store. Please note... you do not want this environment near your other environments or your Mossm may not want to use it!
