Star Coins

Star Coin 1: Early in the level, you will see the Star Coin blocked by some meteors. Jump off of the top meteor to find some more meteors with a ? Switch on top of one of them. Press the switch and one of the below meteors will explode, providing access to the Star Coin.

Star Coin 2: After the checkpoint, you will see a ? Switch that you need to hit to progress. Instead of dropping down immediately, wait on the right ledge and eventually, the meteor in front of you will blow up, letting you get the Star Coin.

Star Coin 3: You must jump precisely in between the wheel of four Spinning Spiked Balls to get this Star Coin.
