Cube Baby is a familiar in The Binding of Isaac, added in the Repentance DLC.

Spawns a frozen ice cube familiar that cannot move on its own, and requires Isaac to kick it, causing it to slide around the room and deal contact damage to enemies.

The cube can be kicked by walking into it, melee attacked, or be shot at. It can also be picked up by using Mom's Bracelet.

The familiar deals up to 11 contact damage based on how fast it's traveling, 4.29 times per second.

The familiar will slow enemies it touches while moving.

Enemies killed by the familiar are frozen, and obey the same rules as ice statues created by Uranus.

The familiar blocks enemy projectiles.
