Hermitcraft 8 : Mumbo Pranks AFK Grian 

1:11 I want that music piece and I want it now

I FOUND THE CLIPS AND THEIR OG SOURCES Both in-episode on their main channels. For Grian's perspective, start about 5 minutes in on S8 Ep18 For Mumbo's perspective, start at about 14.5 minutes in on S8 Ep23 This took me like 15 minutes of skimming the episodes after calculating based on upload dates- Also, to the person who posted this video, providing links to their channels would be more helpful than an @ [ meant neutrally; just as a general tip ] though linking the specific video the clip is from would also help.

The fact that he just stood there and watched himself die 2:39

What episode is this? (Grians pov)

I want the piece of music from 1:39ish. I aksed on a couple other videos, and no one seems to know.
