When Kelsey demolishes a wall at Craig's house, her father takes away her sword. So she enlists Craig and J.P. to help prove to her father that she's still worthy.
Craig and his two best friends, Kelsey and JP, are always going on adventures in the untamed suburban wilderness known as the Creek - a kid utopia where tribes of children rule over tree forts and bike ramps, making up an entire kid society. Each episode finds the kids either venturing into unexplored areas of the Creek, encountering new Creek Kids, or just getting into trouble at their hang out - the Stump.
It's Halloween at the Creek, and Craig is on a mission to collect as much candy as humanly possible, but a spooky ghoul from the Creek's past threatens his haul.
