Mermaid and a waving starfish

The mermaid holds up a hand and demonstrates: you wave like this. The starfish watches carefully, then waves back — with all its arms at once, because it has five and could not choose between them.

Make the starfish the brightest thing on the page: orange or pink. Keep the mermaid's tail in a calmer color so the starfish is not lost. Plenty of scales here for a long quiet session.
