Contributions to Hermitcraft 6Edit
In Hermitcraft Season 6, Mumbo's fifth season on Hermitcraft, the Youtuber lives on a group of small islands off the coast of the Futuristic District. On the largest island, Mumbo constructed a treehouse that was later removed because it didn't fit the futuristic theme. Mumbo has also built a bunker beneath the island, that was later flooded with water. Mumbo argues that a post-apocalyptic theme is still futuristic, and has left the bunker. Mumbo's storage system, a massave sphere on top of the largest island, dubbed the 'MumBall', is currently the biggest build of Mumbo's on the server. Mumbo also plans to terraform the islands into blockier shapes, and construct a mob farm on the second-largest island. Mumbo has also built a mob grinder and slime farm underground. Mumbo has also begun turning his largest island into a futuristic city, and constructing many farms.
In the shopping district, Mumbo has constructed his 'Iskallium Shop', where he sells slimeballs, and a 'Spoiler Store', where he told players they had to pay a fee for spoiling the shop before his video came out. However, after the video came out, the store became useless, and was later repurposed as a 'Film Store', where Mumbo will a film advertising other shops for a price of 64 diamonds. So far, Mumbo has made only one advertisement, for Xisumavoid's Instant Repair store .
Mumbo Jumbo and Grian created an alliance, known initially as Build Stone, but later changed to Architechs. Grian realised that, combined with Mumbo's redstone skill, they could achieve a lot more than Grian's building could do alone. This was also strengthened by the fact that Mumbo and Grian were already good friends, and Grian, being new to Hermitcraft in Season 6, didn't know many of the people on the server. Mumbo and Grian constructed a messaging/mailing system between their bases to send messages to each-other when one is offline, and to keep others from knowing their plans. Mumbo and Grian also created a machine that removes Mumbo's mustache, and randomly places it somewhere else on the server. They now charge people three stacks of diamonds to run the machine. Mumbo has also created a redstone water-elevator for Grian that takes advantage of the new 1.13 water mechanics to shoot Grian up to a given floor.
Outside of HermitcraftEdit
Mumbo alternates between posting Hermitcraft and Redstone videos on his channel, daily, skipping Monday. His older redstone videos have been mostly tutorials, where Mumbo shows how to construct a redstone contraption, and showcases, where Mumbo shows off a redstone build he has made. Lately, however, Mumbo has been showing his process of creating contraptions, by taking on challenges, and experimenting with new ideas. He sometimes issues challenges to viewers, and then creates a video later showing off the best contraptions he's found. Mumbo also has a series called 'I build your silly redstone ideas', where he constructs several redstone builds suggested to him, generally on his Twitter . Mumbo also has a very old series called '20 doors in 100 seconds', where Mumbo constructs 20 piston doors, and showcases them by walking through all of them in under 100 seconds.
Other Minecraft Videos
Mumbo occasionally posts a non-redstone, non-hermitcraft video. Some recent examples of these are "Things only ORIGINAL MINECRAFTERS Remember! ", "20 SMALL Features in Minecraft That Make it GREAT! ", and "How to BUILD NEW THINGS in Minecraft! ". Mumbo also occasionally makes videos about Minecraft life hacks, and does experiments to help him play more efficiently.
Mumbo also has a second channel, which Mumbo calls the 'Filming Channel'. This channel was called 'Mumbo Vlogs', untill later changed to 'Mumbo'. On this channel, Mumbo will occasionally post short films, or mini-documentaries. Mumbo has spent some of the last couple of years attempting to, and learning to make, high-quality short films.
