help please(this is recommended for happy boom friend fans but anyone can answer)

I'm writing a fanfic about what would happen if happy boom vrienden 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 meer 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 boom friend for chapter 3 would be appreciated, thanks.
