Nick and Tesla's Robot Army Rampage

As the story opens, their Uncle Newt takes a consulting gig at a cut-rate amusement park, engineering animatronic figures for a cheap Hall of Presidents knockoff. One perk of the job is that Nick and Tesla have unlimited access to the amusement park all summer long - but the kids quickly discover that one of the park employees has a sinister plan. They'll have to build a few robots of their own to foil him! Ages 9 to 13.
