Ham 'Em High 12-4

Ham 'Em High 12-4 is the 4th level of the first theme in Ham 'Em High.

Strategy
Loft a Yellow bird and accelerate through the middle structure. With a little luck, you can detonate the central TNT and clear the level with a single bird if the upside-down stone triangle doesn't stuck between the two vertical wood blocks. Otherwise, fire a Yellow bird into the top of the first stone tower and detonate the TNT beyond.
