Several of the tiles in Rocko's Modern Life: Match-Master are based on different cropped areas of promotional images used on other tiles. There are two tile sets based on a promotional image showing Rocko and his friends on a couch watching TV - one that shows the entire image, while the other is zoomed in on Ed and Bev Bighead. The tile that shows the entire image does not crop out Ed and Bev, leading to what could be considered, by technicality, partially duplicate tile sets.
