Charlie and Lola - Season 2 Episode 6 I Am Collecting a Collection

Charlie has been making a collection of plastic dinosaur figures from cereal and Lola decides that she wants to start a collection too. However, she finds that it's harder than it seems. Her idea of collecting water is dismissed as "boring," and she tries collecting leaves, but it's nowhere near autumn. Nevertheless, she gathers a set of objects that don't seem to be a collection, but in fact have their own special way of going together.
