Rainbow squishing the big belly she got after eating too much. To be thin and healthy don’t do like her, avoid fatty foods and snacking. XD (TBH, I love her “Wake up!” outfits X3)

Possible story:  
Rainbow: Oh geez… I really let myself go…
 
At the end of the year, with all those fatty foods in large quantities at Thanksgiving, Christmas and New Year’s Eve meals, it’s easy (especially for girls) to gain weight. Even athletes are affected, Dashie got fat and now have a big belly after eating too much at Applejack’s massive Thanksgiving feast.  
Exercising and losing this weight won’t be easy with such a big tummy. To make matters worse, Christmas, New Year’s Eve and its fattening meals are coming. Unless she can get back in shape before 24th December, it seems Rainbow will stay fat (or maybe obese) for a very loooooong time. At least, the others Mane 6 will be her workout buddies.
