In this round you'll face bats and guys in jars throwing snakes. When you reach the blue pot, head into it. There is a key below you in a blue pot. At the end it's best to jump onto the platform when it's at its highest and then jump over the barrier, as if you try to destroy it the croc may catch you first. If you hit the pot into the right-hand cleft you'll get the usual item-catching clouds stage. If you hit it to the far far left you'll reach a strange miniboss battle. This enemy throws projectiles diagonally upwards followed by straight ahead, and takes three hits to kill. The blocks contain a helmet. Once you have a key head to the right. Activate the door block and sink beneath the mud. Head to the right then immediately start jumping across, because deadly lava will start flowing down behind you. When you pass the blocks you are safe. Ride the blocks up and grab the potion, then jump on the spring to reach the next area.
In its default position the pot here takes you to the key area. If you hit it to the left or right you reach an area with crocodiles, a crossbones and some meat. Jump into the mud and head left. The blocks contain a bag of gold, and the pot you just swam under leads to the cloud area (which will be empty if you've already cleared it). Jump out and into the area by the door and sink down. You'll land on or near a helmet. Then swim up to the exit.
