Freeze a fish:
 To freeze a fish in its place, select "Create-a-Fish". 
 After your fish is created, chase a fish. If it runs, 
 press [Esc] to pause the game. Move the pointer over 
 the fish, then and click and hold. If the caption states 
 that the fish is "Looking for a place to hide", chase a 
 different fish. If it states "Running from" your fish, 
 resume game play. The fish will stay in the same place
