Lady Sauvi created her own dragonballs and hatched an eternal dragon, this gift was a wedding present to Cooler and Icying. This dragon has the same wish capabilities as Shenron, giving 3 wishes. The only stipulation is that one must be part of the royal family, to use them. (Because of this, yes, Frieza can use them)
