Can't move Kidnapped Child (SPOILER)

cd CaveOfDisgruntledTrolls
You have moved to CaveOfDisgruntledTrolls. The cave is dark and smells
like... feet? Oh, right, it's probably the trolls. There's a
scared-looking kid in a cage by the far wall.

There is no undefined here

As a result, I can't mv the child out of the cave. I tried this with the dummies and the box and anywhere else with the mv command, to the same results.

I rmed the trolls but nothing happened. There's no way to rm the Hideous Troll, even with sudo (there is no implementation to sudo rm the hideous troll)

If I move the hideous troll into the cage, I can't inspect either the child or the troll. I can't move the troll out either.

I even tried the advice from like 7 years ago on an earlier post about this issue by moving UglyTroll into the Cage.

It's not recognized once i try to less it(the troll).
