Metamato

The Metamato is a type of food appearing in the game Kirby's Epic Yarn.

The Metamato looks exactly like a Maxim Tomato, except that it is made of yarn. The item used to belong to Yin-Yarn until Kirby walked by and ate it. The angry sorceror turned Kirby into yarn and sent him to Patch Land.

In this new world, Kirby saw a blue yarn boy named Prince Fluff being chased by a monster. Kirby tried to inhale the monster, but the air went right through him. The pink hero suddenly transformed into a car and saved the prince.

Upon being ingested, the Metamato has given Kirby the ability to transform at his own will.

Trivia

 * The Metamato could be a pun on metamorphose, which means to change form, and tomato.
