Walt Disney Home Video "Neon Mickey"/@comment-71.61.156.2-20130727161532

I was in first grade about 5 years ago, and I remember watching Pete's Dragon on VHS. I was scared but I just said, "Whoa, that wasn't expected!" My friend was so scared. But I don't understand why they called Mickey Mouse 'evil'. Why couldn't they've used Steamboat Willie instead.
