In a few cases, brief animation glitches actually inadvertently cause the villains to become more frightening than the animators originally intended with the correct designs. The two best examples of this are The Sky Skeleton ("The Scary Sky Skeleton," The Scooby and Scrappy-Doo Show) and ("That's Monstertainment!," 13 Ghosts of Scooby-Doo). There are several others, though I picked the two most obvious examples.
Below are the comparisons:
I suppose you could argue this is more of a fun "opinion" than a fun fact of the week, so what do you all think? Does the animation glitch genuinely make the villains more frightening in these two cases?
