Here is how Rarity's human version is making her dancing skills in G-Merl's Eternal Quest.
(After doing "Life is a Runway" music video)
Human Rarity: (have an idea) Idea!
(Human Rarity put on her Rainbooms outfit)
Human Rarity: Let's dance.
(Human Rarity got a great big paper, and got a pencil to draw, and gets ready to make footprints to make dancing skills mat)
Human Rarity: (looked down at her footprints and see a stain on her boots) Oh my!
(Human Rarity placed her pink heeled shoes on the paper and then, the footprints are shaped like her footprints.)
Human Rarity: Okay. Fabulous.
(The pink heeled shoes helped her dance, it felt wonderful.)
Human Rarity: That's better.
(Rarity got her pink and blue pantyhose, part of her Rainbooms outfit.)
Human Rarity: (checking her shoes by tip dancing)
(The bottom of her shoes were tapping away as she danced)
Human Rarity: Oh my.
(And so, Rarity stepped on an ink pad and began "Life is a Runway" moves.)
Human Rarity: (looked at her feet) I'm getting the hang of this.
(Each step, she danced away till the music has stopped.)
Human Rarity: Oh dear. We'll time for the next song.
(Later, Rarity cleaned her floor, in a flash. She put on the song "Smooth Crimina by Michael Jackson", and started to dance again)
