Undertale Yellow Halloween Hack

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.

Undertale Yellow Halloween Hack is so funny, it makes me wanna merge without looking!
