In this entertaining feature for the 3- to10-year-old set, the wicked witch Hydia (voice of Cloris Leachman) and her two nasty daughters, Reeka and Draggle (voices of Rhea Pearlman and Madeline Kahn) are scheming to flood Ponyland with a strange liquid called Smooze. The ponies find allies in the Grundles, who have already been made homeless by the Smooze. The challenge is to stop the witch and her daughters, send them back into their volcano, and retrieve the lost land of the Grundles from under its cover of Smooze -- not to mention protecting Ponyland from the worst. Not an easy agenda, even after several adventures gear everyone up for the grand finale.~ Eleanor Mannikka, All Movie Guide
