"Calm yourself, Zossie. Those must have been the Pokémon known as Sudowoodo. A most interesting Pokémon. I wish I could research them further. They must be mimicking plant life in an attempt to avoid their weakness—water."
Phyco quote in same area in UM:
"Oho! These Sudowoodo are fascinating Pokémon as well, worthy of being a research topic all on their own! The way they mimic plants in order to avoid water... How very interesting."
Do you not understand the logic here? Sudowoodo is a ROCK humanoid creature, a rock formation, that pretends to be a tree to discourage Water-types from getting close to them. Sudowoodo make Water-types believe that they are Grass-type, and since Water is weak against Grass, prevent those Pokemon from attacking them.
