The 1987 Sneak Peek figure is not popular. Were it not for his oft-lost microphone, no one would care about him at all. The figure is named after the son of Stephen King. But, again, no one cares. But, I've long found this figure to be extremely useful and fun to have around. I've used him both as an army builder and an individual character. There's a decent amount of content out there on him, though. Here's the best of him from around the web.
