Grandpa Petson and the cat Findus were busy cleaning up for Christmas. And they had almost finished everything. All that was left was to take care of the Christmas tree and the festive table. And just then something happened that was not supposed to happen. Petson slipped and hurt his foot so badly that he couldn't go to the store to buy groceries for the Christmas table, let alone the Christmas tree... And so it would have been a sad Christmas for them if Petson hadn't had guests whom neither he nor Findus could have even dreamed of.
