 * Throw the crate at the caterpillars, go right, and climb up the platforms on the second tree.
 * After the third platform, go left, grab a crate, and toss them at the caterpillars.
 * Continue up, grab a crate, push when you see a ninja squirrel come flying down.

Boss: Owl
This bird will fly across the top of this screen. Grab a ball and keep moving to avoid his feathers. Once he comes down, get out of his way, and when he goes back up, toss a ball high in the air. Run away from the ball, or you'll get temporarily stunned. Repeat it four more times, and he'll be history.
