The No-fruit is a transforming fruit. The No-fruit's first and only appearance was in the episode "The Froggy Apple Crumple Thumpkin," and is the first fruit introduced on the show.  

Appearance

The No-fruit looks like a block of tofu with two green leaves on top. Once a leaf is plucked off of the No-fruit, it rapidly transforms into a wide variety of different fruits, and will halt when the fruit is struck with a blunt object.  

Flavor

When Chowder ate the fruit when the leaf was not yet plucked, he complained that it had no flavor. But once the No-fruit transforms, it takes on the flavor of whatever fruit it becomes, only more flavorful than it was before and than the original version of the fruit as Chowder described an apple as "super appley."

Trivia

• When Mung says to hit them at the right time, Chowder hits a un-transformed no-fruit by accident. Nevertheless, it still functioned like an intact no-fruit when the leaf is plucked.
• The No-fruits are seen in the games Bookin' Cook and Rump-A-Thump.
• If a No-fruit is hit at a certain time, it will turn into a hostile, juice-spitting creature. Different members of this creature's species are seen in Chowder's Girlfriend.

• The time between the different fruits changing gets faster as time goes on.
