Bop is a super-cheerful puppet who is optimistic and always makes the people around him a bit happier. His older sister, Kade, is much less happy and more mysterious.
Bop is a hand puppet with fair skin. Like another fan-made character, Announcer Hand, Bop's eyes change color through the different videos. His eyes are purple in An Oobi Vacation and blue in An Oobi Christmas.
