Top: the Japanese and US versions of Super Mario Bros. have a one-block gap above the pipe leading out of the water in Worlds 2-2 and 7-2. If Mario is in Super or Fire form, it is very easy to get stuck in the wall by ducking on the ground and then swimming into the gap. Mario will get sucked into the rocks and be unable to escape, with the only option being to wait until the time runs out to restart the level.
Bottom: in the European release, Nintendo has corrected the error in the simplest way possible. Rather than patch out the glitch that results in Mario being sucked into the wall (it can still be performed in other places in that version), the developers simply added a block to close the gap.

The Japanese version of Mario’s Picross contained four puzzles that were cut from all other versions for depicting objects not appropriate for children, such as a cocktail, a beer stein, a cigarette in an ashtray, and a glass of wine. These were changed to more appropriate images: a Boo, a bird, a rabbit and a top hat respectively, for the other regions.
