Hasbro uploaded today The Canterlot Movie Club in Russian to their channel on YouTube (like other few versions) but in description there is summary of short from Digital Series (ealier they did the same so I’m sure it comes from there).
 
Translation (I don’t speak Russian well also my English is not the best but you should understand it) below.
 
Twilight volunteered to look after principal Celestia’s garden while she was away. At that time equestrian magic took over the garden! Plants began to live their lives, dance, sing and grow at incredible speed. Fortunately, Applejack appeared on time and the girls managed to tame the disobedient jungle before Celestia returned.
