I really think that Super Friends : Going Bananas is highly age-appropriate for my four year old nephew. The plot is pretty silly, not unlike that of
T. Rex Trouble, but it is just totally up my nephew's alley. The story isn't scary, and the pictures are non-threatening, and the two combine well enough to excite my nephew and make him interested in reading books. We both like these Super Friends books because they feature many superheroes and emphasize team work and cooperation in taking down the bad guys.
