My Little Pony: Friendship s Magic. Imagine what would happen if one episode featured the CMC getting their cutie marks. Oh, that idea already happened. Well, how about we have a castle for Twilight. That already happened as well. Geez, I wonder if one episode would involve adult Spike. Oh what's this! Another idea has happened already. So we the fandom has to make up our own episodes. Like this:

Lamest Pinkie Pie

Pinkie Pie becomes lame and abandons her love of parties.

Now you try to make your own episode with their own synopsis. See what you can come up with. Good luck!
