Tip Number 1: This is in space, gravity is off alot so if you're on flat planets long jump like crazy but be carful spin near a wall and you will fall.
Tip Number 2: Bowser< FALCON PUNCH!
Tip Number 3: Try to get on Yoshi from behind cause from the front will send you flying to the side if he moves.
Last tip: when in doubt use you platforming powers and backlip and wall jump to the star of victory.
