An American Tail: The Treasures of Manhattan Island

Fievel (voice of Thomas Dekker) and his friends Tony (Pat Musick) and Tiger (Dom DeLuise) learn that buried treasure lies beneath the ruins of an old subway tunnel in Manhattan. But when they go hunting for the goods, they stumble onto something surprising. Fievel meets a group of Native American mice who fled the streets of the city when European mice arrived, fearing they'd be plagued by war and disease like their human counterparts.
