Kids race shopping trolleys round the shopping centre car park after closing and splat each other with pickups from mystery shopping bags: water balloons, a rocket powered baguette, a watermelon mortar, bananas, an egg carton shield, a point magnet and a leaf blower. Drift for a boost, jump the ramps, and climb the trophy road through eight arenas from Aisle Nine to a space port loading bay, twelve carts from a pram to the Mega Trolley, free Loyalty Card stamps, daily jobs and five modes.
