Super Mario Galaxy/Toy Time Galaxy

Toy Time Galaxy is accessible in the Engine Room with 40 Stars.

Star 2: Mario Meets Mario
For the time being, ignore the Hungry Luma you meet on this level.

Star 4 (Fast Foe Comet): Fast Foes of Toy Time
This is the same as the hidden planet in Star 6 (see below), except with faster moving enemies and platforms.

Star 5 (Purple Comet): Luigi's Purple Coins
This is a difficult star to get. You land in a corner space of a very large area that forms an 8-bit Luigi. Every space of the area is a hazard, except the platform you start on. The green spaces start to disappear once you step on them, the yellow spaces begin to rotate when stepped on, and the dark green, swampy area will immediately make you lose a life when touched. There is also the ever-present danger of falling off, of course.

As usual, the goal is to collect 100 purple coins which are scattered around the area. Once you obtain 100 coins, the star will appear on the platform where you started, so try to move in a circular path. There are a total of 150 coins in the entire area so it is OK to miss a few. There is no reward for getting all 150 coins, so don't look for one. Occasionally there will be small groups of coins (about 5) in a clump off the border of the area. To get these, a very efficient way is to jump toward them, and quickly spin to move yourself to the cornered square. There will also be large gaps where coins are in a line. Long-jumping is the best way to get these coins and to get to the other side. Lastly, don't worry about the clock. You have plenty of time to complete this so stay focused mainly on not falling.

Star 6 (Hidden): The Flipswitch Chain
Enter Star 2. Proceed through the level as for Star 2. When you meet the Hungry Luma, feed it Star Bits.
