Abusement Park

Walky appeared as a Demon beast sent by Nightmare Enterprises to King Dedede in the episode Abusement Park. Customer Service suggests (somewhat jokingly) to hold a Karaoke contest with it, the grand prize being Kirby's favorite food, Watermelons. Kirby would stand on the "stage" (actually the NME Teleporter) and be sent to NME to be destroyed by the overwhelming numbers of Demon Beasts there. After several attempts to get on to the "stage" and sing (his attempts denied by Mayor Blustergas, Chef Kawasaki and Sir Ebrum to name a few) Kirby inhaled Walky and became Mike Kirby. Kirby then proceeded to sing Kihon wa Maru badly, but Customer Service sent him to NME anyway. However, Kirby's bad singing destroyed all the Demon Beasts and was sent back to Dreamland. By the time Kirby had finished singing, he had destroyed Castle Dedede. In the end, Kirby wanted to sing again, but Walky ran away. Possibly because he didn't want to be inhaled again... Strangley, Walky had no attack of his own and simply acted like a regular microphone (exept he can talk, which he prefer not to do).
