This episode of TfTD is about little boy Timmy(Seth Green) being picked on by his jerk step-dad while his mom tries to be as nice as possible to him. Meanwhile, at night in his room, there is a boogeyman in his closet, an octopus under his bed and various other demons. There are some geniunely scary moments and young Seth Green does a great job. You might classify this episode as one of those "happy ending" ones, but it needs that ending or it would be a worse episode.
You can find it on VHS volume 5 of Tales from the Darkside.
