Trivia[edit | edit source]
- This item is a tribute to Edmund's cat Guppy. 
- This item may also be a reference to the Schrödinger's Cat thought experiment.
- It is possible to obtain two collars by finding one in a Red Chest, without picking it up, and then finding another collar in a different Red Chest. However, this does not have any additional effects and does not count towards transforming into Guppy.
- Resurrecting in a Curse Room may trap Isaac if he has no way of recovering health or exiting them without losing health.

Bugs[edit | edit source]
Bug! When the Keeper is resurrected by Guppy's Collar, there is a chance it spawns with half a Soul Heart as health. When a health upgrade is obtained, the Keeper will have 1 coin, as well as the half Soul Heart as health. When a second health upgrade is obtained, the Keeper will lose the half Soul Heart and have 2 coins as health.
Bug! Guppy's Collar can be exploited to gain infinite lives. When Isaac's last will is on the screen, close the game, re-open it, and continue the run. Isaac will appear to die again, and will also have a separate chance to be resurrected.
