Misty miscasts a spell and ends up pulling all the main six ponies into her magic spellbook, where they are sent on an RPG style series of quests to eventually battle some cave monster as their only means of escaping from the spellbook. At first, I thought this should've been another special long episode so we could see all of those quests, but after how ultimately pointless the whole journey apparently turned out, I now think what we got was probably more reasonable. As for that final boss they must battle, in typical MLP fashion, rather than beat him in battle like they were told to, Misty ends up using her cutie mark magic to discover he's lonely and offers to be his friend, which the beast gladly accepts. Oh, and the one who sent them on those quests is some kind of book fairy who seems bored with everything, though she is pleasantly surprised by the final outcome of their journey and agrees to send them home anyway. Overall, I found this to be a nice fun episode, but not much more than that.
