Moira has the perfect birthday planned. "I want to invite grade 1, grade 2, grade 3, grade 4, grade 5, grade 6, aaaaand kindergarten." Mom says no, so Moira asks her dad.
Dad says no, but somehow everybody in every grade "...aaaaand kindergarten" shows up for the party. The house is full, and the kids are hungry, but luckily Moira knows what to do to save the day.
