In this episode of Hermit season 10, Mumbo works on the giant laboratory that goes on the end of Magic Mountain row - this build is the biggest in the area, and it took me over 3 days to make and 2 days to design/concept art. I'm really proud of everything! Filming channel: https://www.youtube.com/user/ThatMumboJumbo2 Instagram: https://www.instagram.com/officialmumbo/ Twitter: https://twitter.com/ThatMumboJumbo
