Frozen Factory: Zone 4

Red Star Ring 1: When you come to a boost at the beginning o🌠f the level, jump over it and onto the raised platform behind it. The Red Star Ring is on the next platf🐻orm after that.

Red Star Ring 2: Impossible to miss, the second Red ༺Star Ring is at the end of a line of rings midway through the level's first 3D sequenc❀e.

Red Star Ring 3: Another one that's difficult to miss. This one൩ is near the end of the se♐cond 2D segment, in the middle of a room full of pink octopi.

Red Star Ring ꦯ4: In the area in which you need to proceed upwards by turning the nuts, keep to the left and find the fourth Red Star Ring tucked into a little alcove in the center structure.

Red Star Ring 5: After returning outdoors, you'll pass through five pistons in a row, and then a loop. After a long jump, you'll land on a sheet of ice. Jum𒆙p and press the Y button to pound through the ice to the pistons underneath, on top of which you'll see the Red Star Ring.
