Needless to say, fish fingers are on the menu! Shell pasta salad with peas and sweet corn will be the perfect side dish.
Here’s a fun idea for the cake! Make 1 pack of blue jelly in advance and pour into a round container with flat bottom, approx. 10” in diameter. Put in the fridge.
The day of the party make a vanilla cake in a 10” diameter pan. When the cake has cooled place the “sheet” of jelly on top of the cake. Use cookie dough or marzipan in different colors to shape a whale’s tale (in black), colorful fish and a boat and place on top of the blue jelly. The jelly will look just like water and your cake will resemble the sea with as many sea creatures and boats as you want to add on top!
