During the Credits
The first two minutes of the credits of Mr. Peabody & Sherman include animated backgrounds and silhouettes of various characters and random objects from the movie. The rest of the credits scrolls over an animated background of simple drawings depicting the interior of the WABAC machine and the eras traveled to in the movie.
After the Credits
There is an animated 2D drawing of Mr. Peabody and Sherman (in the style of how they originally appeared on The Rocky and Bullwinkle Show half a century ago) waving at the audience, turning around, and walking into another time machine.
