Bowser in the Sky

Bowser in the Sky is the final Bowser level in Super Mario 64, in which Mario would travel through platforms in the sky until he reached a Warp Pipe leading to a fight against Bowser to save Princess Peach and the Toads in Princess Peach's Castle. Mario would have to avoid enemies such as Chuckyas and Goombas.

Stars
There were two hidden stars in this level, like all Bowser levels in Super Mario 64; one for collecting all 8 red coins, and one in which only appeared when you pressed a star-shaped switch.
