Upon reading an ancient book from a long-lost civilization, Twilight accidentally unleashes an army of creepiness upon Equestria. However, these characters seem to have been downgraded on the scare factor due to them being ponies now.

Rainbow Dash and Applejack find themselves staring at Twilight Sparkle's plot. To throw, or not to throw? Screw it. Rainbow Dash throws the snowball, and the sound of it impacting Twilight's flank is sooooo worth it. Or is it?

This means war.

Again, poor wording, author, poor wording...

Pinkie Pie just bought some bananas.

Pinkie pie discovers a documentary about the rainbow factory. She gets twilight to use that one spell in "Sonic Rainboom." and take her to cloudsdale to see if it's real. I know it sounds stupid, but just read it.

(Taken place prior to "Wonderbolts Academy")

Skyball is the most popular aerial sport in Equestria and well known around the world. The princesses decide to hold an open tournament, the winning team gets 1,000,000 bits in prize money and a chance to face off against the Wonderbolts themselves in a final game.
Seeing her chance at stardom, Rainbow Dash assembles an unlikely team to play in tournament. Can the Ponyville Pegasi rise to the occasion, or will they be grounded by the competition?
