You have 30 ticks of the clock at the start of this level, and the only way you can make it through while collecting everything is to move as fast as your legs will take you from + Clock to + Clock. You really don’t have time to mess around!
These wooden crates contain a Super Star, which can help you deal with the enemies that try to get in your way for a short time.
Green Star #1
Just over a small rolling hill occupied by Spiny Skipsqueaks is a Green Star Ring. Two rows of Green Coins appear on nearby rolling hills.
Always look for shortcuts or easier routes. For example, rather than deal with these rolling hills, use the alcove here, collect a + Clock, and avoid the hassle from the enemies as well.
When you get inside the catacombs and reach the split, the top route is not only faster, but it also lines you up to collect a Green Star.
Green Star #2
If you took the upper route, you can jump off an invisible cloud platform to reach the second Green Star.
Green Star #3
At the end of the lower route is a pipe that takes you to a bonus room with two Spinies guarding it. Light up all the color panels in the room as quick as you can; the Green Star appears at the top of the stairway on the left side of the room.
Falling off the rollers isn’t the end of the world here. In fact, if you lack a ranged attack it might be safer for you to do so to avoid having to deal with the Spiny Skipsqueaks.
