An American toymaker, Jakks Pacific, is launching a line of five dolls based on Skechers' popular Twinkle Toes characters. The two companies have also developed a series of 11 “webisodes” about the adventures of the four “Twinkle Girls” that are being released twice a month on the website. Skechers says that its Twinkle Toes collection has been its most successful line of children's footwear since its introduction in 2008.
