In the author's defense, the mogwai were advertised as gremlins:

The magnitude of the Gremlins bait-and-switch still baffles me. They marketed it as a family/kids' film; it was a horror/comedy for adults. How did the studio think that was going to play out?

Anyway, unless you've seen the film or heard people like us rant about it, it's a pretty easy mistake to make.
