This level focuses on Mushroom Trampolines and a new enemy, the Hop-Chop. In the first little area you can just ran past the Mushroom Trampolines and hit the blocks as you go for some coins, but you need to climb the wall ahead. Up top you’ll find a Red Ring and collecting the eight Red Coins will reward you with a Fire Flower .
Continue to climb, jumping up the Mushroom Trampolines to the left side where Green +Clocks can be found. At the top defeat the three Hop-Chops to find that one doesn’t disappear and instead becomes a portable trampoline. Position it against the back wall and launch yourself up to a nook with Green Star #1 then pick up the Hop-Chop again. Quickly run across the giant Mushroom Trampolines to the Checkpoint Flag then go up the steps. Position the Hop-Chop underneath the moving Mushroom Trampolines and bounce up, using them to reach Green Star #2 cleverly hidden above.
Clear out the Stingbies then check the back wall for a Fire Flower amidst the ? Blocks before bouncing up to a ledge with the Mystery Box. Here you must quickly defeat the Hop-Chops and bounce up to Green Star #3 before the 10 seconds expires.
After exiting the Mystery Box you’ll find a large moving Mushroom Trampoline that will take you through some Para-Biddybuds. The first ledge has a ? Block then it turns to a large swarm of Para-Biddybuds with the Stamp at the center. Claim the stamp then try to get some 1-Ups by jumping on them before using the Warp Box.
In the Goal Pole area, use a Hop-Chop to help cap if you lack a Cat Power-Up.
