What do you think an episode celebrating FIM's 10th Anniversary would’ve looked like?

Many cartoons and shows that run long enough air episodes that celebrate how many years they’ve been around, celebrating milestones like 10 years, 20 years, etc.

My Little Pony: Friendship Is Magic has had a couple milestone celebrations honoring how many episodes have been released (100th and 200th episodes), but the show only had 9 seasons, so it never got an episode celebrating 10 years since its premiere, with the show having its finale a year short of a whole decade.
