Somewhat happy with this one. The idea is to try and get an x-ray/internal view of the inside of a mimic once our heroine has been captured.

V1.3:

I've hopefully now fully resolved the depth issues. The lora really tries to put the girl in the box. Even if prompted with stuff like "from above" it'll still create an illusion of depth, which I'm very happy about. Tentacles can still appear outside of the box which is unfortunate but it looks far better than a leg.

I recommend a strength of 0.8-1.2.

mimictrap, mimic chest, closed chest,

Trigger words, won't work without them.

in container, 

Helps with stability alot, you'll get more open chests without them, but if thats what you're after, go for it.

tentacles, tentacle sex,

A given, due to the nature.

restrained, tentacle pit

Adds tentacles around the girl's body. Tentacle pit will generally add more tentacles.

{color} tentacles

I now do recommend prompting the colour of the tentacles. There are varied colours in the dataset so if you don't, you may get a multitude of colours.

I like seeing what you create with my stuff, so feel free to post anything you generate!

V1.2:

As always there are sometimes depth issues but this iteration has ironed most of them out, hopefully. Sometimes it'll try to render the girl on an open chest in the style of a normal mimic chest, especially if you prompt it with stuff like "from above", usually this is fixed for a particular seed by increasing the strength. Please however accept some general instability while I refine it.

I have a little suspicion its slightly overtrained, due to the fact you have less of an area to work with (as the chest covers a good portion). It can generate many scenes inside the chest though, but alot of the scenes can look similar due to the chest taking up the screen, I guess.
