Toilet paper mascots

Almost all products have descriptions of usage either in photos or text, except packs of toilet paper. When ever you see a pack of toilet paper, there is always some sort of animal mascot on it, even though that particular animal has nothing to do with the use of the toilet paper. When one brand have a sheep as their mascot, another brand have a squirrel, and another have a pig on it, should this mean that a sheep, a squirrel and a pig have something to do with wiping someone's behind? This should only mean that these items are meant for wiping clean either sheep, squirrels or pigs. The most accurate image for toilet paper packs would really be a person wiping his filthy portal of relief as this is what it's meant and used for, but I suppose having images of fluffy critters on the packages will sell more than what should be featured.
