A school that wants to take part in the project must have its own Paddington Bear mascot. The main task for the class/school joining the project is to create a blog or website describing adventures of the bear. Each pupil in the class takes Paddington Bear mascot home for a week. The mascot becomes a member of a child's family. The pupil writes (in his own mother tongue) an entry in Paddington's diary describing things the bear did during the week they spent together.
