A mold from Lego Media that could never be made as a real part

[Takanuinuva]

Just as the title says. Are there any lego parts specifically made for lego games or media that would never work as a real life part.

Concerning artwork for minifigures, yes! Many minifigures in renders don't "work". The arms are usually bent out of place or at the elbow, legs splayed out and / or twisted so they are not an integer number of studs wide, heads often at an angle compared to the neck piece.

Although they are more realistic now than they used to be.  Try bending the arms and legs of Aragorn and getting two hands on his sword like this ...

And as for Gimli's legs, the real minifig cannot even sit down.

Aside from minifigures, I can't think of any pieces from media that should be considered 'impossible' to see in real LEGO.
