Some friendships are too special to give up, even if they're imaginary! Having Outgrown his fantastic pal Bloo, young Mac has placed him in the tender care of Madame Foster's Home for Imaginary Friends, with one condition-Mac must visit daily or Bloo will get adopted out. The third season of the beloved cartoon sees Mac, Bloo, Wilt, Eduardo, Coco, Frankie, Mr. Herriman and Madame Foster monster fighting, entering talent shows, facing fraudulent foster homes, going to Europe and tackling flea infestations (it can't always be fabulous!).
