Looks like we have the synopsis for episode 10! Geez, soon enough we'll know half the episodes from the season. It goes by so fast...
Anyhow, get the description after the break and thanks to Edoardo for sending it in!
"Applejack's plans for an orderly harvest go awry when Apple Bloom becomes obsessed with catching a magical creature she thinks can help them."
