What makes this plausible but impossible how Micky is in a dream. He dreams of going in a reverse world and this shows him transferring to the other world. What makes this impossible is that you can't walk through a mirror and transfer somewhere else. You can't just transport somewhere else where all objects are alive. Objects don't just come to alive and try chasing you.
A nutcracker doesn't just take the nut its cracking and eat the shell. Nut crackers don't just come alive and eat the shells thats impossible. But how Disney makes it look plausible is use human emotions and make act like a human inside an object. Micky realizes its a nut cracker and the emotion on his face tells that he is like "woah" this isn't suppose to do it. He doesn't know yet he is in a world where everything comes to life.
This screenshot is of Micky getting ready to shrink after eating a but that the nutcracker cracked. This is impossible you can't just start growing and getting smaller and changing that dramatically. How its possible is that we see the changing join on and we know something dramatic is going to happen this is illustrating that Mickey is transforming. They needed those changes to show he was going to change if you didn't have it it would just be big Mickey now little Mickey.
What makes this plausible is that Micky was playing with the cards and then became one of cards by getting shuffled into the deck. He became one of the cards, what makes this impossible is you can't become a card and fold into a card and be smashed into the cards.
What makes this plausible is he is fighting off the cards in the story and he uses the pen as a ink gun. He is shooting the cards with ink to distract them and make his escape. What makes this impossible is you can't shoot people with ink and the cards wouldn't be chasing you this is a show of being defensive and guarding. but in real life you can't shot cards with ink in a show of that defense and cards wouldn't be chasing you in the first place.
