Sudowoodo

“Although it always pretends to be a tree, its composi­ tion appears to be closer to a rock than a plant.”

— Pokémon Gold

“It disguises it­ self as a tree to avoid attack. It hates water, so it will disappear if it starts raining.”

— Pokémon Silver

“If a tree branch shakes when there is no wind, it's a SUDOWOODO, not a tree. It hides from the rain.”

— Pokémon Crystal
