From the Super Mario Wiki
Snoodles are a type of enemy in the game Super Mario Galaxy 2. They look like a regular plant with a thick green stem and a blue head at first sight. However, when Mario or Luigi approaches one of them, they will reveal two eyes. Their only method of attack includes trying to block the brothers from advancing by leaning towards a set location. These enemies can easily be defeated with a Green Shell or even by the light shone by the shell itself. Also the player can shoot two Star Bits at it or even just Spin into it to defeat it. They first appear in the Cosmic Cove Galaxy, and later reappear in the Slimy Spring Galaxy.
The name Snoodle, may be the words snail, an small animal and noodle, another word for pasta.
