As I was watching Robin Hood (the good old Walt Disney, Robin Hood and Little John walking through the forest Robin Hood) I realized a few more discrepancies. The holes in Little John's shirt and Robin Hood's hat, after being chased in the opening by 'the scheming sheriff and his posse,' disappear. A similar thing happens on Fox and the Hound when Boomer (the woodpecker) knocks on the widows door. He punches a hole through the door (after all, he is stuck in the door when she opens it) but the hole is never seen again.
Anyway, back to Robin Hood. At the end when Robin Hood swims up using the reed, if he had been breathing through it there wouldn't have been any water in it to blow in Little John's face. Also, when Skippy shoots his arrow into Prince John's backyard and he comes face to with Maid Marion, I wonder how the birdy ended up on Maid Marion's side of the court when it had in fact gone down Lady Cluck's dress. And also, how does that cast help the blacksmith dog when it is so loose on his leg?
