Episodes suggesting a friendship
In Yeah, Who? I Wanna Know!, Puffball does a little song after Gelatin asks who the host's gonna be, singing "Yeah, who? I wanna know!" (hence the episode title). Firey is then put in a trance, but then breaks free of it, then answering that TV should be the host.
Episodes suggesting a conflict
In The Long-lost Yoyle City, when Team No-Name is close to putting W.O.A.H. Bunch up for elimination, Puffball dropped the rest of her team just so her team will lose and she can get the prize. The first contestant she dropped was Firey, though this was probably a coincidence.
