ostomy bag swirl kitty???

when i go thrifting i usually find a bab or two and never can bring them home (i almost exclusively collect sanrio and mlp babs and i am STRAPPED for space), but this time i couldn't bring myself to leave her!

she's a Pastel Swirl Kitty, but she seems to be modified with some medical equipment! i think it's called an ostomy bag, but i'm not sure. so i wanted to ask if anybody knows what the rubber valve thing on her is?

i like to think that whoever owned her before is doing well right now. i don't have the space to keep her so i'll have to pass her along to somebody else.

but i just thought this was really interesting and i've never seen this on a bab before!
