Cool Cool Toon

Cool Cool Toon is a rhythm-based music game developed and published by SNK for the Sega Dreamcast. It was released in Japan on August 10, 2000.

Gameplay centers on a large circle displaying the letters A, B, X, and Y around its edge or in the middle. Players use the analogue stick to move a marker to the indicated letter, then press the matching controller button at the right time. Missing too many letters causes the player to fail.
