Blimpnik

Robotnik's Blimpnik is a dirigible used by Doctor Robotnik during the construction of his Club Robotnik resort. It is modeled on Robotnik's face and costume.

Sonic boarded the blimpnik by disguising himself as a pizza delivery man, fooling Scratch and Grounder. He was briefly captured by Robotnik, using a trap made of leather straps on the inner wall of the blimp, but Sonic managed to escape by tricking Grounder into hitting the release button. Sonic escaped onto the top of the gas bag, pursued by Robotnik and badniks, and Robotnik accidentally popped the bag by shooting it with his Hedgehog Harpoon.
