Fort Bombs Away
From the Super Mario Wiki
The level starts out with a long path and several bombs falling onto the ground and exploding. Along the way are a few wooden structures that can be destroyed by the bombs, some breakable boxes, and Shy Guys. After this is a pit with lava that Poochy must jump over using the Fly Guys. The first Poochy Pup is found right after this on one of the wooden structures. Next is a path with a few floating logs that Poochy can crouch underneath and more bombs. The second Poochy Pup is found blocked by a wooden structure that a bomb must destroy. After this are a few more logs and some Hook Guys which leads into a section with more wooded structures. A red flag can be found on one of the structures while the third and final Poochy Pup is found on another. The final path after this has many bombs, Hook Guys, and Bull's-Eye Bills right before the Goal Ring.
