Guppy's Tail is a passive item.

Effects[edit | edit source]

  • Grants a 1/3 chance of replacing a room clear award with a normal chest or a locked chest, but also a 1/3 chance to replace it with nothing at all.
  • This item belongs to the Guppy set. Collecting three items from this set will transform Isaac into Guppy.

Notes[edit | edit source]

  • The drawback to this item is that keys become much more scarce, while increasing the amount of locked chests. This makes taking Guppy's Tail a potential liability early on.
  • Due to any found chests containing items while in Chest Chest or Dark Room Dark Room, Guppy's Tail can be a good way to quickly stack up more upgrades before facing the final boss.

Synergies[edit | edit source]

  • The Left Hand The Left Hand: Turns all chests into Red Chests, allowing you to get Red Chest items much more quickly (including Guppy items).
  • 15►Mom's Key Mom's Key: Increases the number of drops from chests and counteracts the increased chance to run into Locked Chests.
