Seven feet of snow, four science-fair nerds, one creepy junkyard.
Get ready for the ultimate robot battle.
Jim is tired of being the sidekick to his scientific genius, robot-obsessed, best friend Oliver. So this winter, when it comes time to choose partners for the science fair, Jim dumps Oliver and teams up with a girl instead. Rocky has spotted wild otters down by the river, and her idea is to study them.
But what they discover is bigger—and much more menacing—than fuzzy otters: a hidden junkyard on abandoned Half Street. And as desolate as it may seem, there's something living in the junkyard. Something that won't be contained for long by the rusty fences and mounds of snow. Can Jim and Rocky—along with Oliver and his new science-fair partner—put aside their rivalry and unite their robot-building skills? Whatever is lurking on Half Street is about to meet its match.
