The snakes are back, and this time, there's work to be done! Hisssssssssssssh goes the sound of the brakes. Our colourful, wriggly friends slide into their trucks and roll out slow. They're driving diggers and bulldozers and cranes. There's even a food truck at lunch time; today's special, Ant Tacos! But no time for rest - there's a time crunch! The snakes band together to get the job done, but what are they building? And will the hamsters be allowed to join the fun?
