Octopus Hotdogs and Mac n Cheese

My daughter helped me make the kid dish for our potluck at church this weekend.  It was so simple yet the kids thought it was neat.  Just take a knife and cut the hot dogs to have 8 legs and then boil them.  When they boil the legs will curl up a little bit and look like and octopus.  :)   We made mac n cheese to put the octopus's on top of to be swimming.  :) Do you have any favorite item you bring to a potluck?
