Challenge 28 is a One-Minute Challenge, divided into four rooms with 15 seconds per room. The rooms are as follows:
Room
Description
Room 1
This room's chest is guarded by five Thornsbys, which need to be defeated to clear the way forward.
Room 2
This room features a crumbling floor, under which are gouts of flame. Along the floor are six stranded blue Blippers, which need to be defeated to make the chest appear in the middle of the room.
Room 3
The chest in this room is close to where Kirby starts, but is covered in metal blocks. Kirby can collect a wavy line of medium Point Stars to get enough points for a Star Dash, but the line travels through some Gray Zones above, making retrieving them a bit trickier. Not all the stars are needed, however.
Room 4
This room has a lava pool for a floor. Kirby needs to defeat the five Bronto Burts flying around in the room to make the chest appear to the right.
