Thetford forest will soon be home to extraterrestrial activity, as families are invited to help a famous cartoon character on a mission to find a fallen spaceship.

In the run-up to the release of the Shaun the Sheep Movie, Farmageddon, from October 4, visitors to the forest are encouraged to take part in a mission to get Lu-La the alien home before she is captured.

In a race against time, children helping Shaun the Sheep will need to search for UV puzzles along the self-led Glow Trail with a UV light pen-torch.

Funded by the National Lottery through Sport England, with support from Forestry Commission England, the programme hopes to provide engaging, inspirational and motivating sport and exercise opportunities for new and existing forest visitors.

Trudi Else, from Sport England, said: "There are currently seven million children aged five to 15 in England and nearly four in five are not doing the recommended daily amount of exercise and we see the new Forestry England trails as a great way to start changing that."
