It's a bird. It's a plane. It's a trap!!! It's a hole trap.

Push stickmen into the hole to clear the area. Pushing the same color stickmen with the hole gives you points and a bomb booster. Push them, explode them. Use different kinds of items to push them to the bottom of the hole.

Don't worry about the stickmen. There is a pool at the bottom. Or is there?

Come and figure it out.
