Make a loch ness monster out of doughnuts (Can also be made out of bagels for healthy eating).
Donuts, icing, sweets to decorate - spikes/teeth/eyes OR Bagels/fillings/cucumber, soft cheese, etc
Cut the doughnut in half and stand on the plate this will be the body. Cut the other half in two - one end for the tail, the other for the head. Stand up on it's end. You might need to put a little bit of icing on the base so it will stay up. Decorate Nessie with half chocolate buttons/cut up icing/other sweets for spikes/eyes/tongue etc. Much the same technique for a healthier bagel, but cut the bagel to make a sandwich and fill as required, using cucumber/carrots etc to decorate.
