Theres a way to remove squidbunny in the manor? I feel like I've explored every room in the manor and haven't found a way to remove it in this location
The mirror transformation technically removes it. If you can't craft the cure in the lab due to never finding the recipe you will have enough time to trigger the Jessica transformation and get back to the lab provided you start in the manor. As long as you avoid the enemies you can find the recipe and possibly have enough time to find the recipe to craft with the tentacle egg as well. The item for the tentacle egg should be found before taking the path to the bathroom if you want to find it. I've personally confirmed the first part can be done with zero consumables and the second shouldn't be an issue if you bring any pills or tablets.
