Killroy's Slaughterhouse

Due to an update, the information on this article might be outdated.

Reason: A Killroy prime section is missing.
Please consider improving it by updating the information.

Killroy's Slaughterhouse is a weekly challenge accessed from Killroy in the YumYum Grotto.
In which you are given three randomized selections of rooms (the 2nd selection room unlocks after reaching World 4 and the 3rd unlocks after unlocking it from the Skull Shop).
The random factors are:

• Which class can enter
• What enemy will you be fighting, the map is the same as the mob's spawning area.
  

Killing enemies within these challenges will award the player with  Skulls which act as a currency for the Skull Shop, also provided by Killroy. When the challenge resets(weekly) your Skulls will also be reset.

Rooms can be reset using Airhorn for 400 .
