The kids love the over-the-top randomness of many of the characters and events in the story. The Doctor's secretary and driver is a large gorilla named Judy. Gordito, Dr. McNinja's 12 year old moustachioed sidekick, rides Yoshi the raptor. When we came to an image of Judy the gorilla giving Yoshi the raptor a piggyback ride while he imitate Gordito, both kids said, "I want that on my napkin!"
I was just not capable of rendering the exaggerated facial expressions of both characters late last night. The picture is a lot funnier in the comic.
