Pluto visits Earth in a truly out-of-this-world adventure!

Pluto is not pleased when he learns that astronomers have downgraded him from planet to dwarf planet. He embarks on a fun and out-of-this-world adventure across the solar system to visit Earth and reclaim his planetary status.

Along the way, Pluto bumps into his moons and other planets. But it's a boy on Earth who makes him realize that-big or small, planet or not-he's still special!
