Trained on PonyDiffusionV6XL.

Default appearance: dqslime, slime (creature)

Metal Slime: dqslime, slime (creature), gray skin

King Slime: dqking, slime (creature), fat, crown, smile

Add "no humans" if you want just the slime. Without it, people will probably show up in the gens. They show up with it sometimes too, depending on the pose/facial expressions in the prompt.

Try a few concepts for interacting with other characters too:

holding creature

animal on head

More poses/concepts will work given enough trial and error, check the samples for some ideas

The slime's expression is can be pretty baked to smiling, especially when genning with other characters. Whatever other expressions you put in will be probably absorbed by them. Also, the metal slime "gray skin" tag will be absorbed by other characters too, and you'll probably just get a regular slime. Regional Prompter may be able to get around these issues but I didn't test it with this LoRA.
