Vanish Cap

The Vanish Cap, or Blue Cap, is a cap found in Super Mario 64. When worn, it turns Mario into Vanish Mario for 20 seconds. In this form, Mario can walk through enemies, metal fences, and certain walls. Its music is the same as the Wing Cap music. To use one, Mario must first press the blue Cap Switch in the course Vanish Cap Under the Moat, which activates the Vanish Cap-holding blue Cap Blocks.

In Super Mario 64's remake, Super Mario 64 DS, Luigi gains the ability to become immaterial when he picks up a Power Flower, but the Vanish Cap itself is absent.

Trivia

 * Like the Wing Cap music, the Vanish Cap music is a remix of Superstar Mario's theme from Super Mario World 2: Yoshi's Island, which in turn is a remix of the Super Star's theme from Super Mario Bros., but with an added melody. This theme was reused as the Super Star's theme in New Super Mario Bros., and was remixed as the music for the Rainbow Star in Super Mario Galaxy and Super Mario Galaxy 2.
