Seedot

“SEEDOT attaches itself to a tree branch using the top of its head. It sucks moisture from the tree while hanging off the branch. The more water it drinks, the glossier this POKéMON’s body becomes.”

— Pokémon Ruby

“SEEDOT looks exactly like an acorn when it is dangling from a tree branch. It startles other POKéMON by suddenly moving. This POKéMON polishes its body once a day using leaves.”

— Pokémon Sapphire

“It hangs off branches and absorbs nutrients. When it finishes eating, its body becomes so heavy that it drops to the ground with a thump.”

— Pokémon Emerald
