Moleville

• Initiate the Croco trampoline sequence.

• After the cutscene where Croco blows up the 2nd wall, go back one room and then return to the same room you were in and wait for him (avoid Fireball and the 2 Magmus in the room).

• If you're still short on frog coins, take the lower train track path below the Star Box to find the Shy Guy

• Use star to KO 10 enemies (Mallow isn't guaranteed to learn Snowy at the right time later on if you fail to do this)

• If you didn't stop to get 6 extra coins in Rose Way, hit the coin chest once (most optimal to do this while you have your EXP star).
