This story is a sequel to Goodbye, Boneless

Cheese Sandwich keeps a lot of his thoughts to himself when he's around Pinkie Pie. For a party pony, he's still awfully shy. But today he’s going to slip up, think out loud when he’s barely awake, and say a lot more than he meant to.

Pinkie Pie is always happy to see her friend Cheesie. And this time, it’s not party pony business; it’s a really real visit just to see her! He’s so much fun to play with, and he thinks the nicest things about her, but she wishes he’d say some of them. Listening in is starting to get awkward.

This is a sequel to "Goodbye, Boneless." Technically, if you're trying to read in sequence, it also falls after "Flash and Trend Steal All Your Waffles." CheesePie, of course.

Cheesy Sense sends Cheese Sandwich to the Equestria Games, but it’s also Pinkie’s birthday, and he’d much rather spend it with her. Suddenly, it looks as though he might be able to do both, but first he’ll have to run an obstacle course of his own.
In honor of Pinkie Pie’s birthday and Cheese Sandwich’s appearance at the Equestria Games.

CheesePie, obviously; spoilers for Season 4, episode 24, Equestria Games. It's a one-shot, but if you like, you can consider it a sequel to Mr. Lonelyheart Meets Miss Lovestruck and Slice of Life

As the sun sets and it comes time to close up Sugar Cube Corner, Pinkie Pie receives a letter from a secret admirer.

The Alicorn Amulet twists its wearer into madness and megalomania. Nopony can wear it without repercussions, both for themselves and others. Nopony is safe. Nopony is exempt.

Still, nopony expected him.
