I have analyzed your analysis of the wild scribble and have arrived at the following conclusions. Please note that these conclusions are not a complete analysis and are not meant to be taken seriously, because this isn't I Want to See Your Mental Poop. If they are at all accurate, it's because this is the second scribble. (The first one was almost two years ago.)
StormWalker sees a fish leaping out of the water. The curve forms part of the outline of the fish and the water. It symbolizes breaking away from one's current condition to achieve something better. StormWalker enjoys Chinese mythology, particularly the story about the koi who became a dragon, which means that StormWalker does not give up easily.
Darkfire45 sees Dry Bones. The curve corms part of Drybone's head. Obviously, Darkfire45 really enjoys playing Mario (or just Mario Kart, because everybody loves Mario Kart. Well, maybe not the Wii version). But why Dry Bones? Why not Yoshi? or a Koopa? Because Dry Bones is black and white like the scribble..
weirdlike sees an angry yoyo. The curve forms the length of the string of the yoyo. weirdlike is cheesed that the new TMNT movie was terrible, even worse than the 1990's film series, which was not great, but at least they were fun! Michelangelo is obviously weirdlike's favorite turtle.
And that's the way the world turns or the way the yoyo spins.
I Want to See Your Mental Poop returns January 2015 with Season 5.
