The Pillow Case
As a reward for being NME's best customer, the company sends Dedede a pile of pillows that give people nightmares about Kirby. He announces on TV he's giving out the pillows and, despite Tiff's objections, everybody gets one. Eventually, Tiff breaks down and gets one too. That night, everyone has nightmares about Kirby from previous episodes. Eventually it brainwashes everyone, except Tiff, Tuff, Meta Knight, Sword, and Blade are able to resist it. They rush to Kirby's house where a mob is breaking in. Meta Knight, Sword, and Blade cut open the pillows and find Notties, creatures that causes dreams. Tokkari comes out and says Kirby was asleep all day and didn't get a pillow, and everyone is relieved.
