Killroy's Slaughterhouse
From IdleOn MMO Wiki
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
