Binding of Isaac: Rebirth Wiki

Added in Afterbirth †

Lil Spewer is an unlockable passive item added in The Binding of Isaac: Afterbirth † (Booster Pack #5).


  • Spawns a random pill.
  • Spawns a small Spewer familiar that charges up and fires different types of creep.
  • The familiar and his creep change randomly when Isaac uses a pill.
  • Possible creep includes:
    • A line of damaging green creep that deals 0.4 damage per tick (12 damage per second).
    • A long line of slowing black creep.
    • A line of short-lasting, damaging red creep, with a larger puddle of creep at the end that lasts longer. The creep will deal 1.2 damage per tick (36 damage per second).
    • A short-ranged cone of damaging yellow creep that grows larger and deals more damage the further it travels. It deals 2 damage per tick at the lowest range, and increases to 15.2 damage per tick at the furthest (~6-47 damage per second, based on range).
    • A large ring of long-lasting slowing white creep.


  • Lil Spewer always starts with green creep.
  • The familiar does not do contact damage.


  • Baby-Bender Baby-Bender: Has no effect on Lil Spewer.
  • BFFS! BFFS!: Increases Lil Spewer's size and creep pool length (but has no effect on damage).
  • Box of Friends Box of Friends: Creates a random spewer rather than copying the current one.

In-game Footage[]


  • Lil Spewer is based on this Steam Workshop item by Strawrat and CupertinoEffect.
  • The item originates from Edmund Mcmillen's previous game of the same name, in which Spewer could consume pills to give his vomit different effects.
  • Lil Spewer was first revealed in a tweet made by Edmund McMillen as an official item for Booster Pack 5.
  • In his black form, Lil Spewer resembles Gish Gish, who creates similarly-slowing black creep.
  • In his red form, Lil Spewer has a similar appearance to Super Meat Boy, from the Edmund McMillen game of the same name. In his title, Super Meat Boy also creates blood (the intended resemblance of red creep).
