The Lump is a Monster which can be encountered in The Womb or Utero. It appears as a red lump popping out of the ground, with a gaping mouth and two beady eyes. It attacks by shooting a spread of three shots when Isaac comes within range, then burrowing underground and resurfacing in a different part of the room. Lumps will also burrow underground if the player doesn't come in its range for a certain amount of time.

Added in Afterbirth †

Tar Boys were added in Booster Pack #4.

Like the Lump, the Tar Boy burrows underground and resurfaces in a different part of the room. It will frequently fire a short-ranged spray of shots towards Isaac that leaves behind slowing black creep.

If Isaac is standing in the black creep, Tar Boys can occasionally cause several shots to fire straight upwards out of the creep where Isaac is standing. This can also occur with black creep spawned by other enemies such as Gushes.

Bugs[edit | edit source]

Bug Bug! If you Stun a Lump at the same time that it burrows underground, it will cause their sound effect to repeat continuously for a few seconds.
Bug Bug! If a Lump spawns as a Added in Afterbirth Light White Champion, when the Lump burrows underground, its Eternal Fly will rapidly teleport around the room, potentially resulting in unavoidable damage.
