Randolph Smiley (Robin Williams) has it all--as the costumed star of the highest rated kid's show on TV, "Rainbow Randolph" has a Manhattan penthouse, a Times Square billboard featuring his beloved character, cars, boats, horses and all the indulgence that celebrity brings. Until he gets caught by the Feds in an under the table bribe, busted and instantly reviled, Randolph is a star no more. Enter Sheldon Mopes (Edward Norton) and his alter-ego "Smoochy", a puffy, fuscia rhinoceros. Smoochy is the perfect remedy for what ails the networks...Now it's Smoochy who has the swanky penthouse, the Times Square billboard and the smooth-talking agent (Danny DeVito). Sheldon soon learns that children's television is a dangerous world steeped in corruption, back-stabbing and violence with his biggest problem being Rainbow Randolph. Broke and homeless, Randolph seeks revenge on the Rhino that stole his job and his house; he's convinced the foam rubber carpetbagger is the face of evil sent by the devil to destroy him and he will not sleep until Smoochy takes a permanent dirt nap.
