Super Loud Sam vs Birdman

There's a new villain in town! Brian Moor, aka Birdman, has trained a flock of super smart, super scary pigeons and he plans to take over the country - starting with the town of Topside! It sounds like a job for Super Loud Sam! But there's a problem... Sam's supersonic voice doesn't work. OK, it still works - but not on Birdman's pigeon army. What can Sam do? And can he do it before it's too late?!
