Bumbo Oldoni is a parody of Bumbo Cactoni built by MumboJumbo in Season V of Hermitcraft. He is made out of white blocks like Snow, Diorite, White Concrete and Quartz. He is located in Mumbo's underground temple. There is a wishing well in front of him where players can throw in items. After an item is thrown in, a randomizer decides which one of the two possible outcomes will happen, similar to the Temple of Notch.
A happy noteblock tune will play and Diamonds, Emeralds and Iron will be dispensed from Oldoni's Mouth.
A sad tune will play, Oldoni's eye's will open and water will pour out.
