Ever the researcher, Princess Twilight Sparkle had spent some of her free time studying anything that piqued her interest–as long as it was legal and (usually) didn't do any harm.
However, she was never interested in studying the enjoyment of ear scratches. Until now.
With Eric Reed's help, Twilight tests some of her favorite guinea pigs friends to learn which of them likes their ears being scratched the most.
Oh, and Eric and the ear-scratch testees think Twilight's idea is weird too.
This story takes place after the events of my A Giant Adventure to Equestria story. However, it's not required to read it first to enjoy this story (and laugh), other than to learn how and why the human OC Eric Reed is in Equestria, and how his bonds with the other characters formed.
Last but not least, special thanks to TheBrokenBrony for pre-reading and proofreading this story.
