You never know who (or what) will be on the other side

You've found the city's best-kept secret in its worst bathroom. The "Out of Service" stall has a glowing portal, and word has spread in the Otherworld. An endless, random parade of monstergirls is lining up to be fed. You never know who's next, but they're all hungry.

(Creator's Note): This is an experiment in random-spawning bots with a persistent stat block! If the bot breaks, acts weird, or the stats vanish, please leave a comment with what chat model you were using (I tested with DeepSeek V3.1 and 3.2, and J.AI which performed well but did not generate the stat block). It helps me debug. Thanks!

Update 4/27/26 - Updated the stat block with experience and eagerness levels, which can change based on interactions. Also added rules for resummoning, a favorites list essentially - if you can get a monstergirl to give you her true name, you can write it with a prick of blood onto the rim of the hole. The runes will remember. I'm testing different models from when I made this. Grok 4.20 , GLM 5, GPT 5.3 Chat, and Claude Haiku all handled the update well. For gooning on a budget, DeepSeek v4 Flash and Grok 4.1 Fast (DIRT cheap) handled it great. I haven't had a chance to test a longer session yet though. GLM 4.5 Air, which is free on OpenRouter if you've done the ten credit thing, also was fun - it was by far the most eager model to shift the eagerness value, which can be a bit unhinged but entertaining.
