Later in the episode, he is one of many Crystal Ponies having become depressed as a result of King Sombra's curse. Hearing news of the Crystal Faire lifts his spirits and returns color to his coat and mane.
In The Crystal Empire - Part 2, Rubinstein has other forms of fun at the Crystal Faire, like watching Rainbow Dash and Fluttershy's jousting match. He helps power the Crystal Heart at the end of the episode.
Rubinstein appears at several points in Games Ponies Play, and he appears during Morning in Ponyville in Magical Mystery Cure.

===Season six===
In The Crystalling - Part 1, Rubinstein makes background appearances walking through the Crystal Empire, and attending Flurry Heart's Crystalling. In The Crystalling - Part 2, he appears at the Crystalling when it is cancelled due to the oncoming snowstorm and participates in the evacuation of the Crystal Empire.

He later appears standing in the empire alone.
