The magic, illusions, and the adventure of Fantasmic returns when Winnie the Pooh, Simba, Alex, Aladdin, SpongeBob, and their old and new friends reunite once again with Mickey Mouse to celebrate the debut of the all-new Fantasmic adventure at Tokyo Disneyland's Tokyo Disney Sea park in Tokyo, Japan. But when the devious Heath Lynx from the Benny, Leo and Johnny's Adventures series team up with all the villains from our heroes' past (who were sent by the evil Bowser Koopa), the nightmare is back. Now it's up to Pooh and the others to stand tall against evil once again, restore the imagination, and stop Heath Lynx and the villains plots using the elements of water, light, and fire.
