Mr. Peabody (voiced by Ty Burrell, Emmy Award® Winner—Modern Family), the most accomplished dog in the world, and his mischievous boy Sherman (Max Charles—The Amazing Spiderman), use their time machine—the WABAC—to go on the most outrageous adventures known to man or dog. But when Sherman takes The WABAC out for a joyride to impress his friend Penny, they accidentally rip a hole in the universe, wreaking havoc on the most important events in world history. Before they forever alter the past, present and future, Mr. Peabody must come to their rescue, ultimately facing the most daunting challenge of any era: figuring out how to be a parent. Together, the time traveling trio will make their mark on history.
Sherman is open, enthusiastic and ever-curious. Growing up with his adoptive dad—the time-traveling super-genius Mr. Peabody—gives Sherman myriad opportunities for adventure. Like most youngsters, he has a penchant for trouble and sometimes finds himself in over his head—but Sherman always makes sure to fix even the most difficult problems he’s created.
Mr. Peabody is a business titan, inventor, scientist, Nobel Laureate, gourmand, Olympic medalist, and genius—who just happens to be a dog. Superior intelligence allows Peabody to accomplish extraordinary things, but sometimes it makes it hard for ordinary folks to relate to him—or even know what he's talking about. The one thing that challenges Peabody is keeping up with his adopted boy Sherman. Peabody devotes himself to Sherman, from whom Peabody learns the one thing even a genius has to figure out—parenthood.
Penny Peterson is a double threat—cute and smart. Penny rules her elementary school until she encounters Sherman, who is even more of a “brain” than she is. But Penny’s natural charisma and daring, as well as her caring and loyalty, draw Sherman into a friendship that truly stands the test of time.
