Derpy was delivering mail, flying with all the mail in her Satchel until she falls, she drops all the mail she starts picking up all the mail until she suddenly smells a familiar smell, It's Muffins! There's a muffin stand by Derpy and she completely forgets about her job

Derpy: "I SMELL MUFFINS!!!"

Derpy snaps herself out of her Muffin madness, but she can't help but want the muffins, the delicious smell of Muffins makes her mouth water

Derpy: "I need the MUFFINS!!!"
