Watzit

Watzit is Frankie Stein's pet puppy; he is made up of multiple parts, just like her.

Physical Description
Watzit looks mostly like a regular tan and brown puppy, but he has stitches and some odd parts, including two different-colored eyes (like Frankie), wings, fins and horns on his head. He was in all the books.

Bio Description
"I'm now sure of all the parts he's made of but his pet license is Ten pages long."

Trivia

 * Watzit was made out of many animal parts that Frankie's dad found.
 * It is possible that Watzit may be able to detach his body parts like Frankie.
 * He was briefly mentioned in the second book, however not by name.
