The link will take you to Big Teaze Toys, producer of those adorable yet naughty I Rub My Duckie "personal massagers." (We got three of those among our wedding presents, incidentally.)
Just found out they make other critters. Including Wormie and Fishie.
And OH. MY. GODS. The Duckie also has a Penguin friend!
Perfectly designed for massaging my aching knees, of course.
