There's Finn's ring tone for you. Wanted to use a Finn (from adventure time) song for it and it was pretty much the only good vague options.
This page also references the GeMs trip to Equestria a while back.
Edit: per request, here is the link to my very little guest shot on Friendship Is Dragons. If you don't already read it, you should!
Next page is Wednesday.
Kinda interesting that that's Finn's ringtone for Jake.
BTW, can you send a link to those Equestria strips?
I'm kind of hoping that you'll somehow turn Fusion Cuisine into an arc about introducing Finn's parents to the Gem players :D
So my next suggestion for the break is Baccano! A story of Love, Crime, and Immortality. I'm not actually sure who would play who, but it might be good as a way to introduce Finn on how to play multiple characters at once.
