Wait What? is an activated item added in The Binding of Isaac: Afterbirth †.

Effects

• Upon use, Isaac farts, knocking back enemies and their shots. It also sends out rock waves that deal 10 damage per tick to nearby enemies and break obstacles.
• Shots deflected by Wait What? farts deal 6 damage if they would've hurt Isaac for half a heart, and 7 for a full heart.

Notes

• This item is identical to Butter Bean in appearance.
• Butter Bean has a small chance to turn into this item upon pickup.
• Each run has a chance of replacing Butter Bean with Wait What? in item pools. Both items generally do not exist during the same run.
• This item is useful for opening Secret Rooms, Super Secret Rooms, Bedrooms and the path to Mines. In Bedrooms, it can also open up the passage under the carpet.
  • To break open a secret room, the wall must be hit with one of the rock waves, not the gas cloud, so Isaac needs to stand a few steps away from the wall.
• The earthquake can open Bomb Chests.
• The earthquake can destroy Shopkeepers.
• The earthquake can be used to blow up the Donation Machine or activate/blow up a Shop Restock Machine.

Synergies

• Bird's Eye: Shoots a flame behind Isaac upon each use of Wait What. Despite Car Battery not duplicating Wait What's shockwave, the flame shot is duplicated.
• Book of Virtues: Spawns white glowing wisps on the middle ring that don't shoot. The wisps invoke the effect of Wait What? when destroyed and do not persist between rooms.
• Ghost Pepper: Shoots a flame behind Isaac upon each use of Wait What. Despite Car Battery not duplicating Wait What's shockwave, the flame shot is duplicated.

Interactions

• Car Battery: No effect.

Trivia

• The item description is a reference to a brand of margarine named "I Can't Believe It's Not Butter!".
• Unlike Butter Bean, this item has no unlock condition, meaning it's possible for the player to find it right away, making the joke and reference slightly confusing.
  • Wait What? no longer shows up naturally in any item pools, however it has a chance to replace Butter Bean in any run.
