Part 23

Start by carefully navigating the initial crusher trap. Jump on the block, then onto the crusher, avoiding being crushed against the wall or hitting spikes.

To your left, you'll find a spring pointing right. Hit it and defeat the red Badnik.

Jump left near the red Badnik's location and land in a gap in the left wall above the spring. Collect the three rings inside. (Cream/Knuckles can fly up here).

Exit the gap and jump over a hole with two crushers. You'll see a barrier and Chao #2 on the other side.

Chao #2: Head back left to the base of the waterfall with the speed booster. Use the speed booster and jump hard right before the floor curves down to find Chao #2 on a ledge against the right wall.

Return to the area near the beginning of the act.

Chao #3: This Chao requires Flight, Climbing, or Tag Action High Jump. Jump down to your left to fall back to the beginning of the act. Go up the slopes again. Near the top of the second slope, jump right to where the Green Shield is located (if you haven't collected it).

Continue right, jumping higher to avoid a hole covered by a falling platform.

Reach a wall. Use Flight, Climbing, or Tag Action to ascend and go right. Defeat the lamprey Badnik in the gap.

Hit the spring and land on the tracked platform moving left. Jump off this platform onto a lower one with a spike trap. Instead of re-boarding the platform, jump straight down to the right to land on Chao #3.

Chao #4: Tag Action High Jump is required. You'll see a barrier to the right (the same one passed earlier). Break it.

Jump back on the spring and onto the tracked platform again. Wait for the platform to move down the right side and jump on it.

Ride the platform until it stops. Jump left for the ? Ring Item Box, avoiding the shark Badnik.

Jump onto the moving platform to the left of the item box, then jump up left to a small platform with three rings and a red Badnik.

Jump to the small pole and let it bounce you up, or jump over it, to hit a speed booster that sends you through the floor.

Head left to a waterfall with a moving block. Avoid the shark and climb the waterfall. You can land on the moving block and jump right, or climb higher to jump for three rings.

You'll hit a speed booster that sends you past the checkpoint, where you'll be stopped by a wall.

Jump up right, avoiding a red Badnik, to a machine you must bounce on to go up.

Once up, you can grab the Invincibility Item Box to the right (beware of the lamprey Badnik), then land on the rail to the left and grind.

Grind left until you hit a blue switch on the left wall. Press it to make a platform appear.

A second switch above the first platform makes another platform appear to the right. Jump right from that platform to hit a switch that activates a spring. (Alternatively, use Flight/Tag Action to reach the spring directly).

Hit the spring to be sent upwards into a duct.

The duct will send you running left, then onto the ceiling. You'll fall, hit a speed booster, and go right up a steep slope.

Keep going right until you reach a switch. Press it and get on the appearing platform.

Jump up through the rail, then hit the spring to the right to grind the rail going left.

You'll run up a wall and hit a speed booster. At the top, enter the cannon.

You'll be shot through the floor, then go right past a checkpoint.

Keep going right and grind the rail.

You'll be launched off the rail onto a falling platform. Quickly jump off to the right.

Grab the ? Ring Item Box and continue right. You'll run down, then up, hit a speed booster, and reach a small platform.
