A Bubble Buster (Japanese "Zen-Chan") is a box-shaped, clockwork walking monster with a medium moving speed and good jumping abilities. He's the first monster that appears in the game on stage one. Interestingly, this monster also appears in the graphic tiles of the ROM of the arcade game Chack'n Pop, along with the Stoner and Beluga, but doesn't actually appear inside the game. Super Mode counterpart: Incendo.
