In this round you'll face bats and guys in jars throwing snakes. Anyway, head to the right and get the red potion from the upper level. After that you'll reach a pot. Enter it for the usual item-catching game, except this time there are no lightning men. If you punch it to the right you'll get some items, but if you punch it once to the left you'll enter an area with a crocodile followed by the key in a pot. When you reach the barrier you can either throw potions onto the falling platform to make a hole or else jump onto it at its highest to jump over it. When you return to the surface, head to the right and sink below the mud. Head to the left and grab the potion, then head to the right. Immediately start jumping across, because deadly lava will start flowing down behind you. When you reach the barrier you are safe.

Rather than solving this the usual way, activate the barrier then jump on top of it and immediately jump to the right. Drop down and grab the helmet, then use the spring to surface. The pot here leads to the same areas as the first one, so if you already have the key you don't need it. Hit it to the left until it lands on the snake-thrower's pot, then use it to reach the area to the left. Go into the pot to reach a spring which takes you to the usual cloud area. When you're done punch the pot to the left and jump onto it to cross the barrier and grab the helm to the left. Continue to the left and go through the door.
