My suggestion on this thread was to call them "Pancake Slimes" based on the term they use in marine biology for classifying "pancake" octopi which are also flat/disc shaped compared to their regular round-shaped brethren.

I personally disagree with the term "liquid" because slimes (jelly) are solid, they move by making contact with the ground (jumping) which doesn't make them splash and collapse into a pool of liquid onto the floor, they retain a solid shape while. It's also weird when Fire Slimes are compared with Puddle Slimes and if they are put in the same "liquid" category as Puddle Slimes.

Someone on Discord had suggested to just call them "disc-shaped" slime.
