Any simple graphic edits such as the ones you pointed out in the video can be drawn by yourself from the original SMW grahpics using the 8x8 graphics editor or YY-CHR. (YY-CHR should be used if you plan to make it an ExGFX)
Also, for the future, this isn't where you ask stuff like this. "What is this graphic" questions go here
. But think about if it's graphic simple enough to make yourself before asking.
