The characters are recognizable. Cartman's original cap was not sky-blue with yellow puff and trim, but sky-blue with sky-blue puff and gray trim. Stan's cap was not blue with red puff and trim, but red with purple puff and trim. Kyle's cap was not a bright green duck cap with green flaps, but a yellow baseball cap with orange visor. Kenny's mouth is visible.
In the concluding dialogue between Boy 1 and Boy 2, Boy 2 draws the conclusion about Christmas, not Boy 1.
