Pinkie Pie got in an serious accident and bumped her head. She can't remember anything, she can't even remember her own name or her friends names. The girls worry about her. The doctors at the Ponyville Hospital say that it may wear off as long as you be gentle with her head, even if she is already healed. Rainbow Dash says wants to spend the day with Pinkie while she gets better so she can have a friend to play with, even though Pinkie can't remember a thing.
