Make every enemy dissapear!
This glitch will make all enemies dissapear in the current level, but the level will not end. This let's you to get as many points as you want from eating all the dirt!
1) Get the game down to two Pookas. If you only leave one, it will escape thus ending the round.
2) This works best in horizontal tunnels under the rocks.
3) Get a Pooka to follow you, inflate as necessary to delay him a little.
4) Right when you are next to the rock, inflate the Pooka once to just delay him. When he moves at your character again, move under the rock.
5) Quickly turn around and start pumping the Pooka up. Using the delay of the rock dropping, you should be able to cause the Pooka to burst at the same time the rock drops on him.
6) If you are successful, then the other Pooka will disappear and you can amuse yourself digging out tunnels all day long in the dirt.
NOTE: To return the game back to normal, drop another rock and you will go into the next round.
