Sequel to An Unlikely Couple. Upon hearing that his beloved wife Celestia is pregnant, Discord proceeds to have a midlife crisis. Afraid that the best of his years are behind him, it will take Twilight and Celestia to make the spirit of Disharmony see that fatherhood really isn't that bad. Not only that, his growing rivalry with Luna will only serve to make matters worse...

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...

In an effort to keep her mind occupied, Twilight Sparkle decides to delve once again into the grand mysteries of Pinkie Pie. This time, Twilight's focus is on her claims of growing up on a rock farm: like so many things related to Pinkie Pie, the idea that somepony could grow rocks as an agricultural product makes absolutely no sense. However, the investigation eventually leads Twilight to a rather... surprising discovery.

This is the first story in The Petriculture Cycle.

Or maybe something a little more... colourful?

An unfortunate event gives Princess Celestia a fresh view on her life by forcing her to see the world from a very different viewpoint. With Equestria changing around her, she is faced with a personal crisis... if she can ignore how cute a certain lavender unicorn suddenly looks to her.
