When all of Ponyville decides to take revenge on Rainbow Dash for her excessive pranking, they never expected a genuine zombie to appear. Unfortunately for them he is HIGHLY offended at the 'cookie zombies' and things go from there.
Twilight Sparkle, now the Princess of Friendship, focuses on proving to everypony through the adventures of Season 5 of Friendship is Magic onwards that she truly has redeemed herself for her past actions as Midnight Sparkle.
What if Rainbow Dash overheard Pinkie Pie’s plan to get Everypony to prank her? What if she shut herself in to be safe? An alternate ending to 28 Pranks Later.
After her rainbow mouth prank goes horrifically wrong, Rainbow believes she’s the last pony left alive in Equestria; that is, until she gets a knock on her front door.
Rainbow Dash took her pranks too far. Fluttershy has had enough of her foalish antics and decides to diclipline her in the only way she knows will get through to the mare. Spanking.
This is my opinion on what might have happened in the episode ' 28 pranks later '... enjoy? Rainbow Dash turned everypony into cookie-eating zombies. And there is one last thing she wants to do to apologise.
Alternate ending to the episode 28 Pranks Later. When Rainbow Dash realizes that she had just killed and zombified everypony she ever loved, there is only one way to redeem herself...
The fifth installment of a What If series, that involves the rewriting of episodes. But this collection contains only ten episodes from Seasons 1, and 4-6 (Warning!: Episodes rewritten based on personal opinion, please respect it. Thank you.).
