Umbilical Cord is a trinket added in the Wrath of the Lamb DLC.

It's an umbilical cord with some blood drops around it.

Effect

When Isaac's health is reduced to half a red heart, a Little Steve familiar spawns for the current room.

It has to be triggered by reducing health to half a red heart, so keeping health at half a red heart will not keep this effect.
