So I was giving away a non-MLP playset on Facebook and I decided to throw in a few extra G4s because a) I have a lot of extra Mane Six and b) they fit the playset perfectly. So I set up a G4 Rarity, a McDonalds Pinkie Pie, and a small yellow fakie in the picture.
The lady picking them up thanked me and told me that her daughter was SO excited, and had taken out all her current ponies and arranged them, all ready to "meet the new ponies." So cute!
Another lady contacted me after the playset was already gone, asking about the ponies. "My niece is crazy about ponies." Of course I have TONS of duplicate G4s, so I arranged to give her some other ones.
The whole experience made me happy. First because I was making some little kids happy, second because it was a reminder that G4 MLP itself is making kids happy, just like G1 made me happy when I was a kid.
