To defeat the giant statues, hit it on the eye with a Sonic Wave Guitar Attack when it is open. However, they can also attack. The first is easy. It will shoot big molten rocks at you. Wait until half a second after the eye closes and start the Sonic Guitar. It should be open by the time you hit it. The next one is easier. Stand on the platform to the left and its eye will try to shoot you. Jump to the right and use a guitar. The next two are the easiest. There will be enemies guarding them, but they are pushovers. Hit the missiles that they throw at you back at them (via the Macho Karate Spin). Then, one eye will open, attempting to send out more enemies. Just hit the eye. Do the same with the other one. The last one is actually a mini-Boss (although it has no health bar). It takes three hits to defeat it. First, take out the three enemies in the middle platform. Then go to the closest platform and kill the enemies as you go. Next, jump on the springboard and prepare for a fight. The conveyors will start moving and the eye will open. It will shoot a laser at the front conveyor belt, and also shoot out a ball of lava. Wait until it is done, then jump to the front belt. Immediately use a Sonic Guitar. Do the same thing two more times to win.
