These characters first appeared in My Little Pony Series episode 2 of The End of Flutter Valley. They are stonebacked armadillo with crocodile type mouths.
In The End of Flutter Valley, they first appear to destroy a bridge the Furbobs and other ponies are standing on. The Furbobs explain they have been pushed from home to home by these Stonebacks. Later in the episode Honeysuckle acquires their help to rescues the Flutter Ponies from Bumble and after Megan convinces the Furbobs, the Stonebacks just want to be friends and she herself uses the Stonebacks tunnel under Ahgg when he blocks their way from returning the stolen Sun Stone to Flutter Valley.
