Dodongadon (ドドンガドン,Dodongadon?) , known as Belly Bomber outside Japan, is an elemecha created by Namco in 1994.
The game requires the player to roll five red balls onto the navel of Dodongadon, the titular dragon-like character. Tickets are awarded when players roll balls onto its navel. Dodongadon moves sideways, further increasing the difficulty. Pac-Man and the characters from Cosmo Gangs appear when players are racking up points.
