I plan to add dialogue support/consequences for transformation as I go through and finish the current content (wolf/BE, fox, ram, a conversation after the cat mission). There's room for a bigger ass, might show up with ram's content, if not it'll be added later.
I've been putting out some updates to make the bell easier to get. Now from stage 11 onwards you will always get a bell instead of a pelt if you have the pelt and vice versa, I also tried to clarify more clearly in their gallery entries where it's found. It used to require bust size 3 but now it drops at all sizes and has an increased drop rate if you have a large chest. It can be tricky to find sometimes, still. Cursed items likely will be worked upon with the other characters.
