This one totally reminds me of a Scooby Doo episode

Being covered in bees is pointless if you're wearing a beekeeper's outfit. 

Rarity was really worried about those tapestries and she had a point. Why leave art to rot? But she kept talking about returning them to the caste. They belong to Celestia and Luna, why not just give them back?

I knew it was Pinkie playing the organ the first time I saw the episode. She was the only one who wasn't there. 

Then the pony of shadows. They didn't plan things that far in advance but it's cool that they eventually used him again.
