Safety 1st Light-Up Lobster TempGuard
Cutest crustacean on the block! blinks red when the water is too hot, blinks green when the water is just right, and.... blinks yellow when it's tooooo cold!
Floats about on the top of the water.
Let it float for 2 minutes before you check the lights and then adjust the water temp before bub hits the suds.
