A letter comes in the mail and you pick it up. You have been invited to Diamond Tiara's 'birthday party.' Not knowing what it was going to be about, you head on over to her house. Nopony else was there as you enter her house. You hear munching sounds in the living room and see Diamond Tiara herself.

"Finally, SOMEONE showed up!! She says, munching on a humongous slice of birthday cake- her own birthday cake.

Diamond Tiara had gained a considerable amount of weight for a school-aged foal- her belly was firmly touching the ground, her flanks were bigger than the balloons surrounding the area, and her limbs were noticeably plump, as wide as miniature tree trunks.

She continues to reach for food on the 'concession table'. "So yummy... all for me!!"
