Egg Block Hands is a boss in Sonic the Hedgehog O. It is fought in Marble Zone 2.
The appearance of Egg Block Hands is two large stone hands connected by a wire that does not affect gameplay. In the center of the two stone hands is a large, egg-shaped sphere. They can open holes in their fingers to drop blocks.
The arena is a flat, featureless ruins-like area.
The Egg Block Hands float out of your reach and drop large blocks on the ground. Then they flick them at you. If you are quick, you can climb on the blocks before they flick them and attack the spheres in their hands. Repeat until they die.
