Bon Bon's just found her way into the mirror pool is all. I'm sure Lyra's plenty excited.
Enjoyable enough episode, as the CMC ones usually are (well, they walk the fine line between enjoyable and annoying). Though the bully episode is one that all cartoons tackle eventually, I rather like the way they handled it here, in the sense of the final message just being "tell someone". Because seriously, nuts to all that snitch malarkey, that's the hardcore answer. Go get help. Always works. The true nature of Babs was also nicely foreshadowed with her always covering her flank and looking to Diamond Tiara and Silver Spoon (who apparently just hang around Sweet Apple Acres, waiting to make fun of the CMCs) to see how they react before doing something. Pinkie was a bit forced, but dammit, I loved her float, so it's okay.
Also, the song is freakishly addictive. I can't get enough of it, and imagine it'll be one of the ones that gets remixed more than most. Can't wait.
