Dream Spacewalk

Dream Spacewalk is a dream event in Mario & Sonic at the London 2012 Olympic Games. It is at the Sky Station Galaxy (Syncro Battle Galaxy) from Super Mario Galaxy 2.

Story
A group of Lumas are seen on a planet. Then, the camera scrolls over to Dino Piranha, who spots the Luma. He spots out fireballs and the Luma flee. They go over to the players, asking for their help to defeat Dino Piranha. They turn into Launch Stars and the event starts.

Gameplay
The event focuses on defeating Dino Piranha. Players must go into rings, solo or as a team, and once the ring is fully charged, they launch themselves into Dino Piranha, spin attacking him. After a few hits, Dino Piranha will turn into his orange shade and spit fireballs. Players can spin attack them.

Trivia

 * Strangely, planets from the Good Egg Galaxy and Gateway Galaxy are seen. This is likely the reason for the name change to Syncro Battle Galaxy.
