Maggi is an excellent adventurer, a pretty good songwriter, an aspiring scientist, and Milo's best friend. Milo is a border collie, and he's very smart. When Maggi gets a book about frogs from her grandma, she decides to take Milo on a frog hunt the very next day. But it turns out that catching frogs is hard work. Lucky for Maggi, Milo is there to help. And lucky for Milo, even though Maggi's not the world's best frog hunter, she's the kind of friend who makes everything a little more fun.
