The new cereals are exclusively being sold at Spirit Halloween and Spencer's. The Ursula-themed cereal is a multigrain cereal that's dyed a dark purple color, while the Oogie Boogie box contains a green multigrain cereal that glows in the dark. Both boxes come with a pocket pop figure of the characters and are available for preorder online at spirithalloween.com before they're officially shipped out on Sept. 11. Read ahead to purchase one for yourself.
