Mermaid Mini Game

All it says is, "Each mermaid has a match. And each couple has a favorite place to be. Put each mermaid where he or she belongs." I haven't been able to figure out how to determine where they belong. Anybody know the placements of the mermaids?

You need to match the hair and tail colors of two mermaids on a matching colored rock. I don't remember exactly how it goes, but you would put for example, a pink haired mermaid with a white tail next to a white haired mermaid with a pink tail on a pink rock. I think they have to be facing each other too.

Once I got the hair/tail color connection, it was just a matter of moving them around. There are two blue/green combos and so I saved them until last. When you put two together on the right rock, the rock will light up and the pieces lock so you know those are set.

Hope this helps!
