New update:
Moonrunes google translated didn't make sense to me, but this is what I figured out:
New animation! If you got an egg stuck in ya by the queen, the cute small mermaid will attempt to grab you. If she does, instant GO as she apparently has really strong forearms and will stretch your unoccupied hole to let the sperm swim in while she....cleans your rectum. With her tongue. Just like normal. Same GO scene as normal (aka the only one).
Google translate also mentioned adjusting numbers involving her drowning and recovery or something. Made no sense to me.

By the way: I only recently noticed that you can damage the swamp king by hitting him in the face. His penis is NOT his only vulnerable spot (as I first thought)
