u/Pristine-Letter-6334

So I’ve known OF nendroids but never had one or wanted to buy one since they get pricey but today, a friend of mine wss about to junk her inumaki nendroid and i took it so it didn’t get trashed. I was opening it up and I didn’t like the face she had put on so I attempted to put on the one where he is smiling. I was struggling to get the hair off, so I tried the face itselr and that obviously didn’t work. But since there are sooo many detachable pieces I ASSUMED that the head was also detachable. I twisted the neck, and it popped off. I switched the face with ease until I realized that it was literally just ripped clean off and not a detachable part. It came with this thing that looks similar to the neck piece and idk it ots any help :( what do I do?
