Tentacles Fest: Because why only pink tentacles? This flexible model allows you to create various, colorful tentacles.

Prompting guide (Illustrious):

To describe a tentacle, always put 'tentacles' after the tag. Example: "red tentacles, large tentacles, transparent tentacles, many tentacles, tentacles from ground" etc.
You can add other features like: "scaly tentacles, rough tentacles, soft tentacles, tentacles, veiny tentacles, transparent tentacles, spotted tentacles, gross tentacles, zebra tentacles" etc.
Same for suckers: "white suckers, green suckers" etc.
NSFW: "suspended, bound legs, bound arms, covered mouth" and every other NSFW stuff (oral/****/vaginal penetration", or "imminent oral/****/vaginal").
You can add a monster by prompting "tentacle monster", then describing the monster and adding "monster" after relevant tags. Example: "tentacle monster, giant octopus, pink monster"

Prompting guide (Pony):
