Just a suggestion, but it could be cool if you could control your tentacle pet while messing with yourself, or maybe more events with it like the tentacles actually overtaking the player's body, but at least redirects the player's mind into the body of the tentacles—like a body swap of sorts to like, put more trust and build a relationship with it like you can with Rahi, even if more dangerous.
(... I am suggesting this for totally no particular reason, mhm hm. Totally not because I'm into it...)
