The Icky-Guanas (aka giant icky-guanas and later itchy-guanas) debut in Tough Break for Garrett
The term is a portmanteau of the adjective "icky" with the species term "iguana"
Thanks to their wings, they can fly.
They look like regular ickyguanas, only they're a lot bigger and have dragon wings. The boy one is orange and the girl one is white.
