Fun mermaid games to play online include the "Baking Mermaid Cake Game" and "Jigsaw Little Mermaid Love." Both games are free to play and don't require the player to download anything.
In the "Baking Mermaid Cake Game," players take control of Katrin, a professional mermaid baker who has learned the secret of baking underwater. The goal of the game is to create a birthday cake for the king of the mermaids. Although Katrin has already baked the cake, she needs the player to decorate it for her. The game is played using only the mouse, and players can print off pictures of the cakes they decorate.
