David Hasselhoff saves SpongeBob and Patrick

Some nitpicking about cartoon physics:

• Both SpongeBob and Patrick cast shadows on the surfaces they stand on in the clip - this implies that they're present as three-dimensional objects in space despite being hand-drawn, two-dimensional figures. I was wondering if they appear as paper cutouts in our world, and if they do, is their thickness just as minimal as a piece of paper's?

• What does it feel like to touch them? What's their weight? How can David Hasselhoff pick them up without damaging them? Can he do any damage to them at all?

• They are squeezed by Hasselhoff's muscles. So do they not appear as 2D shapes in our world after all?

• From around 1:25, movement becomes increasingly exaggerated. The beam is shot at Mr. Krabs, then makes contact with the crown, breaks through the ceiling of Krusty Krab, then breaks out of the water, burning Hasselhoff. In each instance, everything in the frame quickly moves down, then back up a notch in a split second; it's barely noticeable, and yet it renders such a strong physicality to the cartoon, that we can feel the "bang" of it all.
