Challenge 17 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 situated in a ceiling cache guarded by two shutters which can be opened by pressing the two switches on the ceiling to the left and right. Kirby will have to contend with the four Crabbos that guard the switches.
Room 2
This room is half-flooded with water, and a waterfall spans most of the upper half. Kirby will need to collect the Point Stars both in the water and in the waterfall to make the treasure chest appear. Two Ink Bottles can be picked up to aid this task.
Room 3
This room features a cyclical water current spinning clockwise. Kirby will need to defeat the four blue Blippers in here to make the chest appear along the top of the loop.
Room 4
This room is half-flooded with water and has a Gray Zone spanning the middle. Kirby needs to collect the Point Stars here, and can use the dash rings to give him a boost if need be. This done, the chest will appear on the right.
