Theo's little dog Potchi is a terrible tease: He keeps running away and getting lost in Paris! Please help Theo find his mischievous little pet. Be ready for an expedition that will take you all over the city north, south, east, and west! Follow Theo from the Louvre Museum to the Gare Saint-Lazare with side trips to the Champs-Élysées and the Zoo at Jardin des Plantes. If you keep your eyes peeled, you'll probably spot some wacky sights. But you may be too flabbergasted to describe them!
