Cherubi

Cherubi, art by Ken Sugimori. Don't be fooled - the sleeping mini-berry is plotting to kill you and all you hold dear.

Cherubi is an official Grass-type Pokémon introduced in Generation IV. It is #420 in the National PokéDex.

It is found in Miato's Quartz Forest, and is the start of the evolutionary line eventually leading into Cherisol.

It is also a perfect indication that Japan utterly loves sticking kawaii-desu faces on vegetable material and/or inanimate objects and calling them creatures.

For more information on Cherubi, see its Bulbapedia entry.
