Kadizmo is a fictional video game which only appears in the online version. At Game Hut (Electronic Hut) a gaming contest was announced through a poster ,but when Greg and Rowley got there,the employee there told them that it wasn't held for a contest, but after Greg and Rowley had shown him the poster, he said that Greg and Rowley can have a contest themselves and put this game on.
Greg explains that in the game your player has to gobble the purple blobs and avoid red blobs. Since the T.V. at Electronic Hut was black and white, Greg couldn't understand the color of the blobs.
