A colorful dinghy with a map motif is attached to the drain stopper and floats as the water rises.

I'm recommending this because my toddler wants me to get this - only he doesn't know that yet. What a great idea for adding art and whimsy to a regular ol bathtub. And anything with a map is cool.

From the MoMA store - $10

Fun element to add to bathtime and works in a practical way too. This drain stopper has a small boat attached to the end of it - kids will have fun and makes it easy to pull the plug on the water when through bathing.
