In the PC and Mac version of Mario is Missing, one of the locations visited by Luigi is the Guinness Brewery in Dublin, which uses this image as its background.

This is baffling since Guinness is famously a dark stout beer (nearly black in color), while the image depicts a regular light beer, in a way failing to correctly depict the one thing it was meant to be depicting.

In Super Mario Galaxy, the battles against Bowser take place on spherical planetoids where Bowser must be tricked into Ground Pounding the blue spots on the floor, causing him to break the glass and get burned by the lava underneath.

However, if he is lured to Ground Pound on the metallic green platforms, he will destroy them and reveal a coin instead. If he does this from a very specific angle, he will escape the gravity of the planetoid and never come back down. Note Bowser slowly moving away in the footage.

There is no way to continue the battle in this state and the mission must be reset.
