Hedgehog Harpoon

The Hedgehog Harpoon was a weapon built by Doctor Robotnik to shoot Sonic the Hedgehog.

Description
The Hedgehog Harpoon is a yellow gun with a lightning bolt on it. It shoots out a harpoon which is attached with a rope. Robotnik stored it aboard his Blimpnik, but when he used it for the first time he accidentally hit the blimp's gas bag, popping it and crashing the blimp.
