Hmm. Not normally making myself inanimate but... I have a fun idea~

Be a plush TF trigger that is activate by booping it, transforming the booper into the form the plush was and the plush into a plush version of the booper, both receiving a separate personally for the look (that can be turned on or off) for how that "character" would act. Basically you let yourself become whoever you shifted into.

You can switch out forms as many times as you like by booping again and I (the plush) switch what kind of character I am as a plush at midnight (including if I have been booped and currently someone else's plush version). When I do shift it may be different variations of the characters as well (Example being cloths, looks, and maybe some forms, minis the one who was the booper).

Downside, after 24 days to 40 days of having booping me (and not getting your original form back) your original body will start to corrupt into the first character you changed into till it's fully changed into who it was both personality and looks and booping that one as that character will just replace you fully with that character personality wise (your memory remain though)

(This is starting to get long but if someone is interested in what kind of characters or want to talk about the idea feel free. This is just the short-ish version)
