Hug Beggar is a machine in Fiend Folio, a mod for The Binding of Isaac.
Does not require anything.
Touching it will hug Isaac, slightly immobilizing his movement until he lets go, after which the beggar will spawn a random heart and leave.
Does not drop anything when destroyed.
If playing as Tainted Magdalene, she will instead use her deadly hug to destroy the beggar and spawn a temporary heart.
