Toot and Puddle are best friends with very different interests, so when Toot spends the year travelling around the world, Puddle enjoys receiving his postcards.
When his cousin Opal loses a tooth during a visit, Puddle dresses as the Tooth Fairy so that Opal's hope of receiving a shiny quarter will not be disappointed.
Opal shares her frustrations with Toot and Puddle when the new girl at school, Bubbles, starts imitating the way she dresses and steals her ideas for class projects.
