I used to have knock down-drag out arguments with writers at Cosgrove Hall regarding their grasp of "cartoon realism".
They used to give interviews to various outlets stating that "the wonderful thing about writing for cartooning is that anything is possible".
Maybe, but that doesn't make it funny.
One guy wrote: Victor sails through the air and drops down manhole. Fortunately his hat brim is wider than the hole and it catapults him back upwards into the stratosphere."
I had a huge rammy with the guy when I told him that Victor's hat and head are not factory-welded as a single unit. Neither does Victor's hat brim have super-kinetic powers, and that cartoons require a certain logic for them to work.
Anyway, onto pogo sticks:
They don't work on sand, but if a kid has no understanding of a pogo stick, i.e. that it's a toy where the user achieves forward propulsion by means of jumping with both feet on a large spring, he will imagine that the pogo stick is some sort of device specifically designed to travel over sand.
