"It's you... Mario, right?! Like our new ship? It's called a Starshroom! We're shoving off soon!" - Captain Toad, Super Mario Galaxy.
Starshrooms are mushroom-shaped starships found in Super Mario Galaxy and Super Mario Galaxy 2. They were built by the Lumas and Toad Brigade for the team to use it to help Mario (or Luigi) on his quest to find all the Power Stars.
