A trunk-like object that comes out of a human's neck, similar to an elephant's trunk, except EXTREMELY long. Extremely painful to grow back once detatched. Also used at power plants to generate electricity.
Guy: "YOU JUST STEPPED ON MY MUMBO AND IT FELL OFF! OWWW!" *grows back instantly, a very painful experience*
Girl: "I'm sorry! But you should probably buy a mumbo bag."
Guy: "A mumbo bag?! What is that?"
Girl: "You wrap up your mumbo and put it in your bag! See, I have one. I got my mumbo bag right after my first detatchment."
Guy: "Sweet! Well, I need to go take my detatched mumbo to the power plant."
Girl: "Ok! Well, good to see that your mumbo grew back nicely. Bye!"
