Laughing Mold is a fungus creature found in the Fungal Lair in the Basement level. After the player has crossed over a mushroom cap into a dead-end corner, trapping themselves, after a few seconds, the music will fade out and the mushroom cap will rise out of the ground, revealing itself as Laughing Mold. A hint that this mushroom cap is different is that it does not dance in sync with the others, and when in the down position, does not move at all. Laughing Mold looks dangerous but just wants someone to critique its standup comedy routine. It can be fought, but it will not attack the player itself as long as they agree to listen. After hearing out its routine, it will give the player an Elixir. If it was encountered before killing the Spore Mother, Laughing Mold will move to the mutant camp in the main boiler room.
