What's with food products having logos and mascots so happy about their own kind being devoured?

Like if you take a look at the Chicken Delight chicken, it’s rushing in, bringing pieces of chicken to a potential customer. Why is it doing that? That’s twisted.
Or the Kool Aid Man. He’s handing out servings of his own insides. I’m assuming that’s how he lives, it’s his blood life. And he’s all giving it out, going, ooooh yeeah. What the hell, man?
Again, let’s look at Twinkie the Kid. What’s he so happy about? Advertising his own people to be devoured. What a mad bastard.
There’s so many food mascots like this. Smiling chips, like that Pringles guy, the California Raisins, those stupid Shreddies from long ago…all in good favor of endorsing themselves and their own kind to be consumed. Reminds me of that movie, Grimm Love.

Okay I guess this is kind of a joke question and maybe I’m taking it too seriously, but I really do wonder; where did that come from? Who thought it would be appealing to have mascots that champion what they are to be eaten? What’s the history behind this? I’ve thought that was peculiar for the longest time. I mean, I wouldn’t go up to some cannibals going, hey man, I taste pretty epic!

Now I realize this is advertisement, and what the purpose is, and that actual cannibals are nothing like in movies much. I just don’t get how that whole mascot thing became appealing. I know there was a Far Side comic about that, but I can’t find it anymore…still, some mascots and logos have some explaining to do.

Humor, history lesson, bring it all. :)
