This level has a bunch of Peepas, Boos, and Big Boos so snag a Beam Box right from the start. Jump on the raft and pass under some chain-link fences or climb up them if you have the Cat Power-Up. If you don’t, then leap off at the platform and defeat the Big Boo before jumping up on the ? Block and over to Green Star #1 .
Continue riding to a long platform where you should defeat the ghosts before progressing. Hop on another raft but look left to see some invisible Cloud Platforms that lead out to Green Star #2 .
To conclude this short level, ride another raft down the river and defeat the Big Boos then leap atop the Beam Boxes, timing your jump to Green Star #3 and onto the safety of a raft then into the Warp Box so you can cap the Goal Pole.
