Hard to find! 1999 Blues Clues Tickety wind up timer- works!

Hard to find! 1999 Viacom and Oral B Blue's Clues Tickety timer to encourage kids to brush their teeth. You wind up the knob on the back (which takes longer now than I feel that it used to), and it takes about 2 minutes for the front to rotate from a white mouth to a bright pink one. The whirring noise it makes is noticeable, but not super loud. It's 3" tall, 3" wide, and 1 1/2" deep. The top and face have some wear, but overall very good condition!
