  • Enemies that touch Isaac will bounce off him and propel in the opposite direction. If they hit an obstacle or wall while bouncing, they will take damage.
    • If an enemy bounces into another enemy, the second enemy will also take damage.
  • When an enemy bounces off of Isaac, there's a 50% chance that Isaac won't receive contact damage.

    • The same damage value applies when an enemy gets bounced into by another enemy.
  • Enemies that don't deal contact damage cannot be bounced off.

    • Lasers cannot be bounced off.
  • The bouncing effect also works against Fire PlaceFire Places and spiked enemies such as PokyPoky, SlideSlide, and GrudgeGrudge, granting a chance to avoid unintentional damage.

  • BombBombs and Troll BombTroll Bombs cannot be bounced off.
  • Belly Jelly can prevent Character Tainted Jacob iconTainted Jacob from being turned into his Lost form by Dark Esau.

Trivia[ | ]

  • This item can be considered a direct upgrade to Collectible Infamy iconInfamy, as the chances to deny projectile damage are equal, but Belly Jelly additionally works with contact damage, unlike Infamy.
  • Belly Jelly is just the brand of jelly beans Jelly Belly®, but the words are flipped. Given the game's theme, this also might be a reference to the jelly spread on the belly before an ultrasound.
  • The costume given by this item is identical to Collectible Bucket of Lard iconBucket of Lard and Collectible Binge Eater iconBinge Eater.
