The Mr. Peabody and Sherman Show is back and crazier than ever! After last season’s cliffhanger, Season 3 opens with Peabody and Sherman teaming up with alter-ego versions of themselves to defeat an evil cyborg version of Mrs. Hughes and fix the course of history! The zaniness continues when the Penthouse is invaded by neighbors, a slippery mouse, a radioactive meteor, a massive storm flood and a full-blown forest with woodland creatures. They also switch bodies, turn into hideous monsters, and discover a rival late-night talk show. Season 3 of The Mr. Peabody and Sherman Show is available on Netflix as of Friday October 21st!
