With your lust for sex satiated, your ravenous hunger makes its presence known with a loud groan. In your new form you have realized that all meat is equal, it is an essential resource. You command your new servant to hunt for meat, and to try to keep humans alive if they are to find any, live humans are a precious resource at this time. She gives you a gruesome grin and slinks into the shadows.
Before you leave, you stretch your roots into the floor, and then detach them. They twist around a bit, and then stop moving, their color shifts slightly to look more like the floor. If anything triggers your trap, you'll know, and you'll be ready.
But with your new addition to the room, you have become even more hungry, and so you enter the halls in search for prey. Your honeypot leaks a little bit of nectar, and emits a powerful saccharine aroma.
You've only took a couple of steps when you notice a rat scurry out from a hole in the wall. It raises its snout to the air and its whiskers twitch. You stop moving. The rat takes a couple steps diagonally towards you, and slowly zig zags its way towards the sweet scent. The pathetic instinctual mammal looks around itself before lapping at your bright nectar. In two swift movements you raise your leg up in the air and smash it into the rat. It dies instantly and you absorb its nutrients through your roots. The small meal hardly does anything to sate your vicious appetite and you continue your search for meat.
Anything could be lurking in these shadows, this house likely defies all logic and reason and is home to innumerable beasts. All the better for you.
