Funny plush series on YouTube based off Undertale Yellow and Undertale Halloween Hack, hence where the combined name comes from. Created by EEVEE_AWSOM, Daniel Movie Prouctions, and Lolmeowaj, the series’ story follows three humans named Varik, Clover, and Raine wandering the Underground with their respective monster companions Mysteryman, Flowey, and Dalv as they try to escape to the surface. Each episode in the series is like an hour long but it’s so goated regardless that even Rob Paulsen shouted it out in Carl Wheezer’s voice.

A criminal organization or "gang" mainly based in urban areas of Columbus, OH. The make-up of this clan is mostly Caucasian individuals, and unexpectedly, about 2/3 of the group's population is made up of homosexual men. Their inconspicuous color choice of yellow was made to allow victims feel a sense of comfort with the affiliation. This is quite the misnomer as Yellow Koala activities include crimes such as human trafficking, wellfare fraud, and manslaughter. They are especially notorious for cases of assault towards young children. They refer to this as "friendly" attacks or "Barney" assault.
