Squidward's Toenail

I was watching Spongebob Squarepants, I saw a scene with Spongebob and Squidward moving a couch in Squidward's house, which was blue all over, then to my shock, Spongebob dropped the couch; right on Squidward's foot! I heard him scream, but Spongebob was still moving the couch, eventually Squidward's toenail came CLEAN OFF! Now I was REALLY shocked! Squids don't have toenails! The place where it formerly was bled a little, I turned of the TV.
