A Picture is shown of the ocean and it is signed by your volunteer. 
Also, a Large envelope with a picture of a Clown Fish hangs in full view.  
A colorful ocean scene board with 6 different clown fish is shown and one is selected by your helper. 

The Big Finish: The chosen FISH matches the one in the envelope and for a KICKER ending- the signed picture now has their chosen FISH on it and they can keep the picture as a souvenir!
