Light-Up Star Wars Rubber Ducks
Rubber Chewquacker, you're the one. Definitely my favorite in this line of Star Wars rubber ducks. Though Duck Fadar isn't bad either. I can see his LEDs lighting up as his duckie butt hits the water, and his labored breath gurgling out, Luuuuke, I am your father...and I say it's bathtime. Actually, the Vader Pond Wars Duck would be a sweet accompaniment to the Darth Vader and Son children's book if you're looking for a gift for a kid.
Star Wars rubber duckies are strange and funky mashups of Star Wars characters Chewbacca, Darth Vader, and a stormtrooper (Pondtrooper) and everyone's favorite waterfowl. Each is fitted with LEDs that light up automatically when they hit the water, and then cycle through a spectrum of colors for added interest (read: encouragement for kiddos not to kick and scream) throughout the sudsing session.
Star Wars ducks come with waterproof, but non-replaceable batteries that have a life of approximately 45 hours.
