With Fox/Blue Sky’s Epic opening in theaters this Friday, Fox Home Entertainment is taking the opportunity to highlight some of their previous animated hits. For a limited time, families can purchase three Blu-ray 3-packs for $21.99 each: a Blue Sky set containing Robots, Horton Hears a Who, and Rio; an Ice Age set featuring the original hit with sequels The Meltdown and Dawn of the Dinosaurs; and an Alvin & the Chipmunks set containing the first blockbuster and its two “squeakquels.” The offer ends this Saturday.
