Overwhelmed with having to choose just one friend to spend time with, Pinkie Pie uses a magic mirror to clone herself.

Pinkie Pie begins to grow upset when she finds out her friends are all doing things that she wants to partake in. Applejack is planning a barn-raising, and Rainbow Dash wants to relax by the poind.

When Twilight Sparkle tells Pinkie she can't be in two places at once, Pinkie suddenly remembers a legend about a Mirror-pool in the Everfree Forest.

Finding it in a cavern deep in the forest, Pinkie recites a special incantation, and a duplicate of her appears, eager to have fun! Pinkie then sends her duplicate off to take part in the barn-raising, while she goes to have fun with Rainbow Dash.

However, the duplicate doesn't get far, when she is invited to a critter picnic with Fluttershy and her animal friends. The thought of missing out on another fun even panics the duplicate, and she rushes to find Pinkie. Pinkie then comes to the assumption that they simply need to make another duplicate in order to not miss out on Fluttershy's picnic.

Going back to the mirror-pool, the two create two more ponies, and Pinkie thinks they are all set...only to have her duplicates make more duplicates! At first unsure, Pinkie is now sure that the fun-loving duplicates will help her situation.

However, they have very little on their mind but fun, and end up ruining each of the activities, and irritating the rest of Ponyville.

Twilight is called to do something, and finds a spell to send the duplicates back to the mirror-pool. However, noone can tell which of the Pinkies is the real one, and Twilight is apprehensive of sending the real Pinkie into the pool.

It is then that one of the Pinkie Pie's proposes that Twilght make a test, one that only the real Pinkie Pie can pass. They would be able to tell the real Pinkie, given that she would stay focused to complete the task to stay with her friends.

Twilight takes the advice, and after Applejack and her family herd the Pinkies to town hall, Twilight gives them a test: watching paint dry. Whoever is able to focus on this without being distracted, will win. Eventually, each of the duplicates loses their train of thought, and Twilight zaps each of them back into the mirror-pool.

In the end, Pinkie learns that it's ok if she can't attend each of her friend's activities, as there will always be more to come to take part in.
