Tie the human creature's hands behind it?

First of all, what a weird thing to say.

Second of all, the 'slave' didn't tie the hands behind him at all! He tied his whole body so the hands didn't become separately tied whatsoever, only tightly tied against the body.

When your boss tells you to tie someone's HANDS, why tie their whole BODY instead?!

Also, when they SPECIFY that they have to be tied 'BEHIND' him, why tie the body in such a way that the hands aren't even behind, but on the sides?

HOW incompetent is this 'slave', and WHY does the ice queen TOLERATE THIS??!

MAKES NO SENSE!!!

And it's a CARTOON, so there's no excuse, like 'live action continuity error' - they knew the dialogue, they could change what they were drawing at any moment, and yet they chose to draw this?!

I can't understand how this process went or why they did it like this.. it's like deliberately producing a continuity error. Why??

Also, the ice queen yells: "Faster, faster!" shortly after this. What does this mean? Does it mean the 'slave' has to whip faster? Does it mean he has to walk faster? Does it mean the 'slave' is supposed to make the human walk faster, and also walk faster himself? The ice queen is so vague with her orders!

The end result of this order is ... two whips and then nothing. The human does not walk faster at all, the 'slave' doesn't walk faster, so what the heck? WHY DOES THE QUEEN TOLERATE THIS? Her order was NOT obeyed (AGAIN)!
