Doodlebug is a part of the Muppet family of monsters! She doesn't know where she came from (nor does anyone!) but she somehow found herself on Sesame Street and has lived there ever since.

Doodlebug has the essence of a kid. She is very naive, which sometimes is a disadvantage to her. Because of her adventerous spirit she often finds herself in predicaments that no one would of ever imagined. She is very brave and curious and likes to explore everything and ask many, many questions that often annoy her fellow neighbors. But hey, she is a kid and they love her anyway!
