The Mushroom was created from a normal Mushroom after being struck by lightning. The Mushroom then blasted Mario & Bowser off the roof and fell on Shy Guy's corpse. This brings him back to life and gives him fairy wings, and Mario and Bowser watch as McShyGuy flies at the sunset yelling his catchphrase, "YEAH TOAST!". It is presumed that this led to the events of SM64: ṩṩἔᾗмὄḋᾗᾄʀ 7 (TOAST edition)'s intro and ending.
This 1-up Mushroom is a Mushroom with turquoise and red color and with Shoop Da Whoop's face on it.
