Hints

The umbrella pig, the rocket pig, and even the balloon pig sometimes self-destruct if they don’t land on a flat surface. i.e. if they hit a corner.

The balloon pig is particularly terrible, since he sometimes floats to an area where it is very hard to reach him. Try to get him before he inflates the balloon. He sometimes wears a beanie, and doesn’t always appear in the same room (or at all) on different incarnations of the same level.

You can time your shot to get past the Wizard Pig’s magic orbs.
