Plan a party to Celebrate? check  
The other fusions that were victims to this ‘state’ couldn’t disagree more. Celebratory was so carefree as always about the current situation, trying to think of a huge list of ways to make the best of it and heighten the mood of many a panicked and fainted mare and stallion. Of course Fancy Pants is in there somewhere straightening his metaphorical tie and monocle and trying to think rationally about the situation maybe he will be able to convince Cheese to dial it back a bit so this little mishap can be hidden from the general populous of ponyville and it can just be a private affair where all may share their current struggles and remedy it with some of Zap’s famous Cider and Sumbutter Cookie’s signature urm ‘cookie’ batter.  
Honestly Celebratory quite likes his(her) new look ‘she looks absolutely outstanding’ were words that were definitely uttered when examining his/herself in the solid oak mirror and experimenting with his wardrobe. Maybe Fancy can use the knowledge acquired here to better design clothes for mares of all shapes and sizes how he’s walked a mile in their horseshoes.
