The Sparkies find a box of bits that they turn into vehicles with joysticks. They discover if they twiddle them, they can make the Robobirds spin round on their perches, Stripy whirls and Sporty jumps up and down when he doesn't want to! Tiny investigates and decides that he's got to stop them before it all gets out of hand. With a quick tweak of the joystick when they're not looking, Tiny has the Sparkies cartwheeling out of control and landing in a heap beside the Nut and Bolt Tree!
