The Crimson Heart's behavior when moving.
The Crimson Heart is a Light Pet item that summons a fast moving bleeding heart that emits dim, red light. It follows the player around, either by rolling or flying after the player. If it falls far behind the player, it will fly through blocks to catch up. It has a 20% chance of dropping from destroyed Crimson Hearts, but it can also be obtained by opening Crimson Crates, which are obtained by fishing in the Crimson.
The Corruption counterpart to the Crimson Heart is the Shadow Orb.
- Normally, it gushes a stream of blood, but if Blood and Gore is off, it instead shoots particles that look like the Cloud in a Bottle.
- Unlike floating light pets, the Crimson Heart will activate Teal Pressure Plates.
