Part 32

Follow this Sonic Heroes walkthrough to find all 10 Castle Keys in Part 32, Mystic Mansion. Includes tips for using Espio and Charmy to navigate the castle and its unique mechanics.

Walkthrough:

1. After a scene, you'll receive your mission. Smash crates and head forward as Espio. Run through loops and hit springs. Charmy will sense keys; grab the first [CASTLE KEY] and the Special Stage Key on a platform.
2. Smash wooden containers in the floor, fall through the hole, grab the capsule, and exit the tower. Defeat the enemy and touch the blue sphere.
3. The blue sphere reverses the castle's orientation. Touch it and hold 'B' to ride a rail.
4. Once off the rail, switch to Charmy and use an elevator to reach the next platform. Defeat the armored searchlight enemy and fly up to the next area.
5. Grab the second [CASTLE KEY]. Drop down, run straight towards two torches to go up an invisible path. Defeat enemies, hit the switch, open the flower, and use the warp.
6. Inside the tower, touch the second blue sphere to flip the castle. You'll reappear near the first Castle Key. Head forward through the now-opened door.
7. Grab the third [CASTLE KEY] in the hallway. Head up the stairs and jump on the elevator platform.
8. Ride the elevator to the top of a big tower. Jump on the platform and grind the rail UP. Grab the ring capsule and follow the path to the fourth [CASTLE KEY].
9. Return to the rail and grind it down. Head forward, hit the checkpoint, and touch the blue sphere to flip the castle. Grab the fifth [CASTLE KEY].
10. Switch to Charmy and fly up to the platform above the fifth key. Open the flower and warp to the top of a tower. Grab the sixth [CASTLE KEY] and warp back.

12. Defeat enemies and touch the blue sphere. Once the castle flips, turn around to find the seventh [CASTLE KEY]. Exit the green pool and cross a second, longer, invisible bridge.
13. Near the end of the bridge is the eighth [CASTLE KEY]. On the other side, destroy crates to the left of the door and pull the switch. Bust the wall to the right of the door and pull the second switch.
14. Head through the door, go straight, and around the platform with the magician. Smash the cracked wall to get the ninth [CASTLE KEY].
15. Head up the ledge with Charmy, defeat the enemy, and activate all three switches simultaneously to open the door. Head through, touch the checkpoint, and go to the back of the huge tower. Drop into the hole and fly to the top.
16. Jump into the hole and proceed up to the
