help please(this is recommended for ppl who watch Happy Tree Friends but anyone can answer)

I'm writing a fanfic about what would happen if happy tree friends and mlp fim met. so far Flippy and Nutty are in mlp world. I'm at chapter 2. Pinkie pie learned that nutty can eat more sweets than her and she told Flippy and he wasn't surprise at all and now i can't think of anything else. also, another tree friend for chapter 3 would be appreciated, thanks.
