Tiny Toon Adventures is a platform video game for the NES.
Before each world, the player can select an alternate character that they can switch into if they find a star ball.
The three alternate characters are Dizzy Devil, Furrball, and Plucky Duck.
Dizzy, Furrball, and Plucky have unique abilities that Buster lacks: Plucky can briefly fly and swim better than others, Dizzy can destroy walls and most enemies with his spin mode, and Furrball can climb many vertical surfaces, slowly sliding down them rather than plunging down.
The second level in each world concludes with an enclosed area where the player must avoid Elmyra and exit through the door; if the player is grabbed by Elmyra, they must start the world over.
