Guppy's Paw

Guppy's Paw is an activated item.

Effect

 * Converts one Heart Container to three Soul Hearts.

Interactions

 * Broken Remote - The teleport will activate whenever Guppy's Paw is used, even if Isaac has no Heart Containers to trade. This can give ??? or Azazel the ability to teleport an infinite number of times without any cost.
 * Guppy's Paw cannot be used without red heart containers, rendering the interaction useless.

Synergies

 * Converter - Switching between the two can give Isaac up to 11 Heart Containers.
 * Dead Cat - The single Heart Container granted on resurrection can be converted into three Soul Hearts.
 * Strength Card - Converts the temporary Heart Container into three Soul Hearts (however Isaac will still lose one red heart container upon leaving the room, if he has any left).

Trivia

 * This item appeared in The Binding of Isaac: Wrath of the Lamb.
 * It is also a reference to Edmund McMillen's cat Guppy.
