After playing my Xbox for a while, I got to thinking, we should have achievements for everything! Then I went to McDonalds and got a Rainbow Dash Happy Meal toy. I thought to myself, "I've unlocked 20% Cooler!" Then I decided to come up with achievements for all the ponies. Here they are:

Get Twilight Sparkle: Make the Magics
Get Rarity: Lovely, Darling
Get Pinkie Pie: Party Time *
Get Applejack: Buck This *
Get Rainbow Dash: 20% Cooler *
Get Fluttershy: Yay
Get Cheerilee: Lesson Learned *
Get Lily Blossom: Previous Generations *
Get 4 ponies: Halfway There *
Get Mane 6: My Heroes
Get all 8: All of My Want
Get 2 duplicates: Come Back Tomorrow *
Get 3 of the same: CMC
Get all duplicates: The Clone Wars
Tell cashier the toys are for you: By Celestia's Beard

(Stars are ones I have achieved)
