Tbh, as much as I love many of the characters from the world of Aaa, I think Fionna and Cake lack in character in comparison to their gender switches, especially Cake. I actually think they're kind of bratty and annoying and not really that funny. Jake has his own kind of spark, but I can't find that in Cake. Feel free to yell at me and stuff but this is just my opinion rofl sweatdrop
