Arnold cracks me up every time. "Nightmare. Arm fell off. Pain free." Like, well, I guess I'll send him home? He seems weirdly fine?
Hahaha, yeah, he's completely fine xD
My thought when creating him was influenced by lizards here on earth, since some of them can drop their tail when they get scared/hunted. So I figured, perhaps this Arnold got so scared during his nightmare that he just accidentally dropped his tentacle. xD
Who knows, perhaps it'll grow out again? ;)
