Lenny and Rini are twin prodigies who frequently cameo in The Railways of Crotoonia. They have yet to speak.


  • They don't have main roles in any future episodes but they are the main characters of Soeren Hermansen's series My Little Pony: Friendship On The Tracks, in which they are the offspring of the original Len and Rin, and are adopted by Princess Celestia when Len and Rin are killed in the 2011 Tohoku Earthquake and Tsunami.
