Here is a recipe that I invented - it doesn't contain any fish but could provoke some interesting debate if divers and surfers are present for dinner.

Shark attack dessert (also known as prop attack)

1 tin of Watties boysenberries

1  bag of white and pink marshmellows

whipped cream for dressing

Method:

Tip the boysenberries into a bowl

Cut the marshmellows up with scissors - cut some of them into twisty and jagged bits to make them look like bits of guts and bone.

Mix cut up marshmellows into the boysenberries.

Put some whipped cream on top to make it look like froth from a feeding frenzy (or cavitating propellor)

It tastes nice and its quick and easy to make.
