At first glance, this doesn't look too awful, just sort of boring. But really look at it. Go on.

It's as if the kids were supposed to be the only ones on the cover but the polar bear was like, "Nuh-uh, ME TOO!" and shoved himself in there. The kids aren't gonna say anything because, well, would you talk back to a polar bear?

Clearly this was an early example of a polar bear "photo bomb."
