The heroes Sonic the Hedgehog, Mighty the Armadillo and Ray the Flying Squirrel was captured by one of evil Dr. Robotnik’s large tank vehicles. The tank threw the heroes into a cage at the Volcanic Vault, where a spiked wall tried to crush them, but the three broke the cage and made their way out, then made their way through the lava-filled Volcanic Vault. Teaming along, the three fight through all of the Eggman Island, which was full of deadly traps. Sonic, Mighty and Ray managed to get to the Island’s control room, but Robotnik decided to activate the self-destruction system of the Island and escaped right after this. The trio barely escaped the blast, and the Island was destroyed.
