Og the frog has always loved making up songs and poems about life in the swamp - about juicy crickets, squishy mud and all of his froggy friends. But it's quite a shock to find himself suddenly living in Room 26 with a bunch of human children (the "big tads"), and an endlessly energetic furry neighbor named Humphrey. He spends a lot of time thinking about his past days in the swamp and all the lessons Granny Greenleaf taught him. But he also has a lot to figure out, and number one on the list is: what is that hamster squeaking about anyway?
