High speed, action-packed, comedy space adventure for six- to eight-years-olds. Working at Grandpa Sat's delivery service with his friends Chrystella the mission controller and Vector the engineer, Rocket Boy is the speediest delivery boy in the entire universe. With his trusty guard sheep Toro at his side he must outwit his mortal enemy, the evil supercomputer Dr Square and his henchbot Trash. They are desperate to discover the secret of his speed, even if it means taking him apart to get it. Rocket Boy Squared: It is a busy day at the Delivery Centre and to make sure Rocket Boy gets all the deliveries done Vector fills him up with a new super-improved fuel. Everything seems fine until a second Rocket Boy arrives. It seems the fuel was so powerful Rocket Boy arrived back before he set off! Grandpa Sat sets both Rocketboys to work delivering parcels. Unfortunately, Rocket Boy 1 flies straight into Dr Square and Trash's latest trap - a portable invisible prison. Back on Planet Cube, Dr Square wastes no time downloading the secret of the Rocket Boy 1's speed before casting him adrift in space inside the invisible prison. It is down to Rocketboy 2, accompanied by Toro, to make sure Dr Square never gets to upload the secret of Rocket Boy 1's speed, and find the invisible prison that contains him. Perhaps Vector's spray paint will come in handy.
