It's an attention getting control thing. Tell him you're not going to do this anymore, night time or naptime, and whatever he throws out of his crib will stay on the floor til morning, or be taken out of the room altogether. If he continues to wake you up, go into the room take all the toys out of the room as quietly as possible, tell him to go back to sleep.
Yes, he's going to scream his head off. Invest in some good earplugs; you're in for a rough time. Kids are going to try this sort of thing occasionally. Welcome to parenthood! They'll try it less if you let them know you're not going to put up with it. You have to be more stubborn than your kids now, just to show them what life is like when they're grown. Never too early for that, I say!

P.S. 7/11?! Eek! That's why we're AF! [chuckle] We're 5/13, and that's only because the Armed Forces Inaugural Committee was only 9 months, otherwise it would be 4/13.
