Bars are obstacles in Super Mario Galaxy and Super Mario Galaxy 2. Bars form walls that completely block hallways, and they are penetrable only if the player character is in their Boo form. Equivalent walls called crystal[1] appear in the first Super Mario Galaxy as well. They function the same way.


Super Mario Galaxy[edit]

In Super Mario Galaxy, bars appear in the Ghostly Galaxy, where Luigi is being imprisoned during Luigi and the Haunted Mansion. They are introduced alongside Boo Mushrooms, which transform Mario into Boo Mario. Shaking Wii Remote makes Boo Mario turn intangible for five seconds, enabling him to phase through the bars and ultimately reach Luigi. Bars are otherwise impenetrable to Mario.

Luigi himself is behind bars. If Boo Mario phases through his holding cell to return outside, he loses the power-up.

During Racing the Spooky Speedster, Boo Mario races the Spooky Speedster in Boo's Boneyard Galaxy. The entire raceway is on a 2D plane. The caverns are blocked by translucent, ghostly walls called crystal that function identically to bars.

Super Mario Galaxy 2[edit]

In Super Mario Galaxy 2, bars appear only in the Howling Tower of Boo Moon Galaxy, the only part of the game to include Boo Mushrooms. Bars behave as they did in the prior game. This area is accessible only during Haunting the Howling Tower. The layout of the Howling Tower is comparable to Boo's Boneyard Galaxy.
