Round Worm

This article is about the monster. For trinkets, see Category:Worms. A Round Worm is an enemy introduced in the vanilla content of The Binding of Isaac: Rebirth. They appear from Chapter 1 to Chapter 4. It will periodically burrow into the ground and pop up in different part of the room. If Isaac is in their line of sight when that happens, it will spit a blood shot in his direction.
