#3: Bad Boy
OK, so animals, as I said above, are pretty darned smart. But we just take for granted that those animals are going to use their intelligence for good, to help those around them. But what if one of these clever animals decided to use their brains… for evil or selfish purposes?
OK, so I’m exaggerating with “evil”, but you have to admit that this story, while hilarious, would also totally work as a villain origin story. He’s a good boy, but when he realizes he gets treats when he pulls children from the river, he starts “arranging” for those children to end up in the river. All he needs to do is recruit other dogs for his racket, and suddenly he’s a canine crime lord.
