10: The two outer planets in Deep Dark: The one where you Rainbow-Starinate those Red Electrogoombas (that's what they're REALLY called, because those blue things at the start of Good Egg are Electrogoombas; the guide sez so), and the deflating replica of the Gateway Galaxy's first planet. 9: Mecha-Bowser Planet in Toy Time. That thing was awsumsauce. 8: The hot/cold planet in Freezeflame. Watching Luigi try to stay away from both the Fire Spike Balls and the rising lava that floods the fire side was epic. 7: The underground 2-D-ish platforming level inside Battlerock. 6: The lazor-beam planets near the Dreadnought. 5: Cyclone Stone Planet in Beach Bowl. 4: Ice- and lava-skating above gihugic black holes in Freezeflame. 3: The Gravity Arrow Switch maze in Gusty Garden. 2: The sinking spire in Melty Molten. 1: The entire Loopdeswoop course! There's lots of potential for shortcuts, and even bypassing the loop itself.
