The ninth book in the New York Times bestselling Rainbow Fish
series.
When Rainbow Fish meets a new friend, Humbert, he isn't sure what to
think. Humbert tells all kinds of strange stories: Somewhere at the
bottom of the ocean there's a plug!
There's a blue whale living near here . . . and he's going to eat up
all of our food.
But before Rainbow Fish and his friends panic, they realize that Humbert
just likes to make up tall tales. Rainbow Fish and his friends soon come
up with an idea that might make them all happy--even Humbert.
