Actually, Orgg, although moleasses are definitely sticky, they are in fact beige, which - despite what the colorblind (*glares at Jigglypuff*) might try to tell you - is not the same as brown.
So let's see, caramel can be made into a stick, and moleasses have been ruled out already, and poop is typically in "stick" form, so by deduction we are left with...
C. Pink Cotton Candy.
See, sugar, from which cotton candy is made, is actually brown before being processed, so once you take away the pink food coloring and the process that whitens the sugar, you have a brown sticky mess that is not a stick.
So, Jigglypuff has the right answer, but for the wrong reason.
(On a related note, some sugar comes from cane, which is a kind of stick, but other sugar comes from beets, which is not a stick. Oddly, no sugar comes from Spiritmonger, which is a beet-stick.
