User blog:Mikel6718/Please Identify this Book/Story

Ok, this popped out of nowhere yesterday, and I'm really troubled by it. I don't really know if it's a GB short story, or part of an R. L. Stine tv series, all I remember is that this is associated woth Stine. So, I remember this (quite vague) plot of an ice cream truck, and kids ate there for free (all they can eat). This fattened them up,  and it turns out the "neighborhood" they were in was a cannibal fest called Nightengale Corners (I honestly don't  know how I remember this name). That's basically it, but I (for some reason) remember the kids getting trapped in the truck forever, and they could eat all they want. Now, I'm not sure about the last part, but the other parts definitely happened. Can anyone help identify this story? All I know is that its R.L. Stine's work.
