This item belongs to the Guppy set. Collecting three items from this set will transform Isaac into Guppy.
Bone Hearts cannot be converted.
Converter: Allows Isaac to attain up to 10 Heart Containers and 1 Soul Heart.
Allows Isaac to attain up to 12 Heart Containers or any combination of Heart Containers and Soul Hearts.
Bethany: Guppy's Paw will remove one Heart Container in exchange for Soul Heart charges. This will kill Bethany if she has no health left afterward.
Book of Virtues: Spawns 3 wisps in the middle ring for every heart container consumed, in addition to granting soul hearts. These wisps have a large amount of health.
Broken Remote: The teleport will activate whenever Guppy's Paw is used, even if Isaac has no Red Heart containers to trade. This can give ???, Azazel, or The Lost (or other characters with no Red Hearts) the ability to teleport an infinite number of times without any cost.
