Oh no! Lovable Amos is heartbroken that his tick bird Amoeba has found a new, fun friend. Even worse, Amoeba’s new friend isn’t even real! Amoeba actually prefers her imaginary friend to her real-life hippopotamus one. Ready to swim any river necessary to regain Amoeba’s affections, Amos sets off on a big adventure—a road trip to the Serengeti— just to prove he’s Mr. Fun. But like most vacations, things don’t always go as planned. Crocodile traffic jams, strange local beasts, and unmarked forks in the river all spell potential doom for Mr. Fun. But leave it to our befuddled hero’s own imagination to turn this disaster-in-the-making into an adventure Amoeba will never forget. As laugh-out-loud funny as the original, Birdbrain Amos, Mr. Fun is a trip kids will want to revisit over and over again.
