Sorry for the delay, was trying to track sources for some of these refs.
Anyway, its petting! With MLP! Be it a Yak, a Unicorn, a Griffon, or whatever else! They all love pets! Up to you if its regular or heavy. Also who is doing the petting!
You’ve got 30 minutes to create followed by 15 minutes to submit! Have fun~
Refs: First one is from Captain Pudge Muffin, couldn’t find a direct source. Pinterest as usual got in the way also.
