Purple Coin Spacewalk

Purple Coin Spacewalk is the fifth mission of Space Junk Galaxy in Super Mario Galaxy. The mission's objective is to collect Purple Coins within a time limit.

Layout
The player will start of in the Assembly Block Planet area, where the Silver Stars were collected during the first and fourth missions. 100 Purple Coins are grouped in the area and the player has to collect them all within a time limit of two minutes. The arrangement of the space junk is different from the previous missions, and some paths may not lead anywhere at all. After collecting all 100 Purple Coins, the player has to use whatever time is remaining to make it back to the starting area to collect the Power Star.
