My kids frosted the cupcakes, cut out the fins from construction paper and stuck them on. Ds crushed the graham crackers into sand, dipped a few frosted cupcakes in to make "islands" and we stuck in some palm trees we had left over from last year. I even dyed the cake blue at ds's request. So incredibly easy and fun. Since I had to transport these goodies to the beach, I sent dh to the local grocery store bakery to buy a box. The bakery people never know what to charge for an empty box, so suggest .50. They'll probably go for it. If you'd like to try this at home, one box for a half-sheet cake will hold 4 dozen cupcakes. Two boxes of cake mix will make 4 dozen cupcakes, and one can of frosting covered them all.
For the rest of the party, I had some awesome beach themed games planned, but when you've got the ocean right in front of you who wants to listen to mom?In case you'd like to have your own beach party, my game plans were: Dolphin, dolphin, shark (duck, duck goose) Red light, green light with the kids doing the crab walk Salt water relay -having the kids race to fill a sand bucket with water from the ocean using a sand shovel. Easy peasy games with no prep, so who cares that we didn't play them. We also served pizza, fruit and plenty of drinks. I found some inexpensive sand toys for party favors (though I did have to search because the school supplies were taking over the seasonal items aisles) and it was done. Oh, one more thing. Emily Post may be rolling over in her grave, but I love e-vite for party invitations.
