Sudowoodo

Sudowoodo is the Imitation Pokémon, a Rock-type that camouflages itself as a tree to avoid predators, though its rock-hard body and unnatural appearance fail to fool even children. Despite mimicking plant life, it is not a Grass-type and has an extreme aversion to water, withering away if given too much. In the games and anime it is often found blocking paths until startled, and it evolves from the baby Pokémon Bonsly.

The Japanese name ウソッキー (Usokkii) combines うそ (uso, meaning 'lie' or 'falsehood') with き (ki, 'tree'), reflecting its nature as a 'fake tree' that lies about being a plant. The 'ッキー' ending also lends a playful, name-like ring. The English name 'Sudowoodo' is a play on 'pseudo' (false/fake) and 'wood,' directly conveying that it is a false tree.
