Escape The Night Season 3 on youtube.
There are multiple barf scenes. The 1st barf scene matpat barfs in the competition where he and Safiya have to eat hotdogs. You can hear it but im not sure if you can see it.
The 2nd barf scene is actually quite a lot, im sorry i forget what ep/competition it is in all i know it matpat, Rosanna, and 1(?) other person are in it and they have to drink three drinks in the beginning. Rosanna barfs a lot im sorry again i skipped passed this challenge because i didn’t want to see it so i don’t know if you can see or hear but they do mention it.
