Octopus/Squid girl for Illustrious.
The Pony version is better BTW, IMO for some things Pony still the trongest model, but Illustrious aint half bad.
NOTABLE TAGS: squid girl, monster girl, tentacles, suction cups
Scylla, monster girl, tentacles, suction cups
Basically "squid girl" for squid girls and "scylla" for octopus girls. But the Illustrious version version kind of struggles a lot with the squid girls.
FOR REFERENCE: This was trained to be used as "concept" lora but it was actually trained as "character" lora because trained as concept lora din't worked that well.
