Here is what AZ says about Uvelipinapia:

“He has a long body because that’s what I gave him for a body. He is Urampa’s neighbor. He does not eat cake all the time. He eats bugs from the ground! He is a bug kind of creature, so he eats all kinds of bugs every day, to get more buggish. His favorite friend is Urampa. They like to sit and eat their popsicles together. Urampa’s popsicle is cake flavored. Uvelipinapia’s has bugs in it. They like to play tag, but they don’t like any other games, not even chess! That’s all!”
