Yoyo is a little rascal and a livewire, cheeky and full of witty thoughts and cunning plans. He whisks through the stories like a whirlwind and is always good for a surprise, either with his crazy ideas or his cocky comments about his companion, Doc Croc. Quick-witted and clever as he is, he always has an answer ready.
