Beat Block Galaxy

Beat Block Galaxy is a galaxy in Super Mario Galaxy 2. This is a very unique stage in which blocks disappear and re-appear to the beat of the music, as the name suggests. Another unique feature is that the Wii Remote will beep three times before the blocks swap. These 3 beeps are also heard in the game. Enemies here include Octoombas and Astro Goombas. Mario can visit this planet after he feeds a Hungry Luma one thousand Star Bits.

Beat Block Planet
The only planet of this galaxy consists of a long segment with blocks that disappear and reappear with the beat of the music. At the end is a pyramid-like structure with five Silver Stars.

Step to the Beep
This level uses music to switch between green and yellow platforms. At the end Mario must collect five Silver Stars. Enemies here are Electrogoombas and Astro Goombas, depending on what color the platforms are.

Silver Stars in Double Time
This is the same as the previous mission, only the platforms are changing twice as fast and the last section is larger.
