The Polar Express was a limited edition cereal based on the film of the same name. It was released in 2004 by Post to coincide with the film's release.
Description[]
The cereal was described on the front of the box to be a "cocoa cereal with marshmallow bits." The back of the box included a maze game and encouraged buyers to "Play 'The Polar Express Train Adventure' on Postopia.com with Code Inside." The cereal itself included brown cocoa-flavored pieces in the shape of snowflakes and marshmallows in the shapes of bells, trains, mountains, white snowflakes, and reindeer.
