Egg Plow is one of Eggman's several vehicles that function as bosses in Bolt the Hedgehog 2: Supercharged
The Egg Plow functions similar to Eggman's drill vehicle from Sonic the Hedgehog 2. However, instead of a drill, it is a plow. As he passes back and forth, just jump on top of him 8 times.
The Egg Plow just drives back and forth, and being hit by it causes damage.
