It's the day of the Biggleton teddy bears' picnic. Evie the Artist makes a poster to tell all the teddies about the big event. When too many teddies arrive, Archie the Gardener runs out of seats and Rowan the Chef runs out of food for the picnic. Ria the Cafe Owner and Bobby the Vet try to help, but as more and more bears turn up, it seems as though the picnic may have to be cancelled. Will the people of Biggleton find enough food to feed the hungry teddies?
