Comic: Rainbows are Magical / Winona / B Assertive!
Comic time! We have an old one above, raggin on poor Rainbow Dash again. It's pretty old, but no one sent it until now!
The first one below is actually from Pixiv, a foreign website. Someone translated it and put it on ponibooru. You can find the original here. And finally some Fluttershy being assertive! Click them all for full.
