Step 1 To make fish, cut small slice off one long side of each egg so that it will sit flat.
Step 2 Cut four 1-inch (2.5 cm) V shapes from red pepper to make tails. Cut radishes and cucumber slices into halves or quarters to resemble scales.
Step 3 Using mayonnaise as glue, place cucumber and radish scales on each egg, covering back two-thirds and leaving space on narrow end for face. Cut tiny cubes from black olives to make eyes and place on the face. Cut slit into opposite end of each egg and insert red pepper tail.
Step 4 Surround eggs with shredded lettuce to reemble seaweed.
