If there’s one type of monster that I’ve barely used in D&D, it’s the ‘Oozes’. Living, wriggling puddles of acidic goop that seep into the walls of dungeons and tombs. The ‘Gelatinous Cube’ is the most infamous of the Ooze-kind. One has a cameo in Disney’s Beyond.
They are some fun applications, but they are never the masterminds (or even side characters) of a evil plan or scheme. They make good fodder for adventure, but I’ve never built a campaign around them. It would be a pretty short campaign.
The Bundimun from Fantastic Beasts is definitely an ooze. Acid texture, amorphous body. It likes to chew through houses and get really problematic when it teams up with its mates.
That last part makes for an interesting mechanic. Not only have I made the Bundimun into a cheeky little ooze that could be easily dispatched, but I’ve also made the stats for a Bundimun swarm that definitely lives up to the warnings in Fantastic Beasts.
Bundimun
Bundimun Colony
The book says that a large infestation cannot be ousted with ease, and can chomped through a building with ease. Based on these stats, a single level 1 character could tackle a few individual Bundimun, but four level 3 characters would need to team up to take on a full colony.
This little quirk you could play with is the spit. Oozes usually try and bop their targets with pseudopods – basically punching out with a stretchy globule of themselves – but Bundimun can apparently spit their acid. I’ve interpreted that as a 10 foot arc, but you could easily add some more range to that.
The main thing about oozes, Bundimun, Black Pudding or Gelatinous Cube, is that they are not very bright and they are slow. On an open battle field, they can be easily avoided. Stick these guys in the rafters or in a big trap and you’ve got a terrific encounter. Bundimun will chew through wooden structures, which could lead to some great adventure moments. Have the ceiling give way above the party, and describe with glee as the swarm rains down upon the party.
Thank You For Reading
Let me know what you think. If you use the Bundimun in an adventure, why not share the calamity caused? You might even inspire me to bring oozes out more often in my own adventures.
