Jailhouse Croc

Jailhouse Croc is the second secret level of Castle Island, and the fortieth level overall in Croc: Legend of the Gobbos. It can only be accessed for those that have collected all 6 Gobbos from Ballistic Meg's Fairway, Swipe Swiftly's Wicked Ride and Panic at Platform Pete's Lair. This level contains the eighth and final Jigsaw Piece needed to unlock the Crystal Island. It is considered the easiest Jigsaw Level in the game.

Walkthrough
Follow the path of crystals through the dungeon. After you turn the first corner, watch out for the Devil Dantini in an alcove on the left side. Once the row of crystals ends, there are two more on either side of the room. You can easily just run straight forward to the door and avoid them.

In the next room, not only do the platforms crumble, but so do the blocks between them. Don't dawdle anywhere, just keep lining up your next jump and taking it. Enter the door at the end. In the next room, the blocks all crumble too. To get the crystals over each block, jump to the first and walk forward to the second before jumping off to the next block. Ahead, just move diagonally across the row of crumbling blocks to the end. Enter this door to find yourself in another dungeon.

Inside, just follow the row of crystals again and keep moving. When you turn, the rooms that open up have Devil Dantinis in alcoves in the sides, but you can just avoid them again. At the end of the path, you'll find the Jigsaw Piece, the last one that you need.
