After a mishap with Twilight's magic, Rainbow Dash finds herself split into seven different ponies.

A very fun story

When one of Fluttershy's dear animal companions wanders into the Everfree, she sets out to bring him home safely - but what she finds at the center of the forest is something she didn't expect, and something that ushers in a change to her world that makes each day darker than the last.

Twilight Sparkle and Rainbow Dash take a walk together, and Twilight teaches Dash the 'pairing game'.
It seems to be an innocent game of love, but Twilight has something else up her metaphorical sleeve...
