The Cannon. Look! A giant cannon! Throw a grenade down the chute, get to a safe place and BoOoOMMMM!!!! The ball will fly out. Go over to the other side of the cannon to find a different pit filled with explosive barrels. Throw a grenade down that chute in order to burn off the barrels, revealing the teleporter. Go through that teleporter to bring you inside your very own cannon. Become your own cannonball and throw the grenade. Light the fuse and BOOOMMM!!!! You're off!!! Fly to collect the crystals and win the game.
