In Super Mario Galaxy, whenever Mario drowns in a swamp, his hand reaches out from under the surface before being sucked in. However, since Mario’s head is so big, he cannot raise his hand above the surface without his head being still visible. To solve this, the game simply shrinks Mario’s head so it doesn’t interfere with the animation.

In Super Mario 64, the two parts of Wet-Dry World do not exist in memory simultaneously. When Mario passes through a certain point in the tunnel, the underwater town becomes loaded and the main level becomes unloaded. By positioning the camera in a certain spot during the transition, we can see that the same elevation is both above ground in the main level and below the ceiling in the underwater town. This means the locations overlap physically, which should not be possible.
