Depiction in the series
Randolph first appears in the season four episode Twilight Time when he accompanies Diamond Tiara to the Ponyville Schoolhouse. Having promised to perform an "amazing, first-time-ever acrobatic display" for her classmates, Diamond instead gets Randolph to perform in her place. While Randolph's display is impressive, Diamond Tiara pushes him aside and takes credit for it.

In the season five episode Crusaders of the Lost Mark, Randolph carries a large stone statue of Diamond Tiara for Spoiled Rich to celebrate Diamond winning the school presidential election. He later appears beside Sweetie Drops during Light of Your Cutie Mark.
