Waffle Cones was the most popular pony in Ponyville by foals standards anyway. Every other day after Cheerilee released her class from school, Waffle would come by and sell ice cream to the eager little colts and fillies.
Waffle also often collaborated with Pinkie Pie and The Cakes for business, a venture that was very profitable for all involved parties.
And soon enough, Waffle might get a boost in business thanks to the extremely eager efforts of a little sister or two.
