Oiled Umberglomp is an enemy in UnderMine. It splits into two Oiled Glomps after being killed. It can change into an Uberglomp after landing in water or into a Fiery Uberglomp when hit with a fire attack. It creates small oil slicks wherever it lands and a bigger slick when attacking. It jumps lightly in the room, but when close to the player, will jump high and damages the player when it lands.
An Uberglomp can turn into an Oiled Uberglomp when it lands in oil.
As it can jump over high walls when attacking the player, it is one of the few enemies that can attack through blocks.
