This LoRA is trained on images of wriggling worms. It vastly improves wriggling motions of worms, tentacles, and similar objects. Tested working for both T2V and I2V.

Include the word "wriggling" as an adjective prior to the object you want to apply the motion to. Works best for long thin objects. May cause some sluggish movement, so recommend adding words like "rapidly" as well if the video seems to be in slow motion.
