 64. 8-second 3D kids cartoon ending. The librarian closes the four books as the superheroes and toddlers wave happily toward the camera. Librarian says, “Remember, return your library books!” The toddlers shout, “We will!” Marcus says, “See you next adventure!” Everyone laughs as the library lights sparkle and the screen fades out.

Marcus is a light skinned 8 year old boy with short black hair wearing a red short sleeve shirt, with a star on his shirt, blue jeans and red shoes with a red hat. He's wearing a blue cape and a red watch on his wrist.
