Challenge 45 is a One-Minute Challenge, divided into four rooms with 15 seconds per room. The rooms are as follows:
Room
Description
Notes
Room 1
This room features two lasers which stretch laterally across four light panels around the room. All light panels need to be activated to make the chest appear.
Room 2
This room features four light panels in a 2x2 grid in the middle of a Gray Zone above Kirby's head, with two in a diagonal pattern already being lit. Two gondolas on separate lines can be used to activate all the panels and make the chest appear to the right.
One easy way to solve this room is to start with the horizontal gondola, disembark after one pass, then use the vertical gondola.
Room 3
Five lasers emanating alternatively from the floor an ceiling block Kirby from accessing the chest to the right. These lasers can be blocked with two swift rainbow rope strokes.
Room 4
This underwater snaking tunnel room is fairly tricky to do quickly. Kirby needs to swim all the way to the right to grab the key, then ride back to unlock the gate to the chest in the lower-left.
