Pufferzine

Pufferzime is an ingredient found in potato chips ordered from Nightmare Enterprises. If eaten, it will cause the consumer's body to swell up like a balloon. King Dedede and Escargoon ordered the chips to make Kirby too big to inhale monsters. It wasn't only Kirby who ate the Pufferzime; King Dedede did as well, but both had the substance removed from their body.
