While on a typical gem hunt with Spike, Rarity uncovers a strange alien device that turns out to be rather handy once you know how to use it.

No, this is not a Fallout Equestria crossover. Just Rarity has a pip-boy.

This story is a sequel to Dear Princess Sunbutt

When Anon takes the liberty to inject his particular brand of humor into Twilight's friendship lessons, Celestia feels the need to respond, more often than not.

A somewhat unofficial sisterfic to 2Merr's Dear Princess Sunbutt

There may not be a response to every letter, and letters 1-11 were taken from my comments in said sister-story.

Please support 2Merr's story too if you like this one. This is written with encouragement of the original author.

EDIT: Apparently someone's done a reading of this and its sisterfic over on Youtube! Why does nopony tell me these things.

Anon takes over Spike’s job of transcribing Twilight’s friendship reports. He does exactly what you’d expect.
