This is a better and more accurate version of the currently hosted SMAS SMB3 Piranha Plants. It has perfectly ripped Piranha Plants, stems and Venus Fire Traps. There are 4 different versions of this that change different things. The readme contains what each version replaces and more information, like what you shouldn't use when using different versions. Credit to me (Telinc1) is not required, but highly appriciated. You can also credit Sonikku for the sprite sheet I used to rip this (link to it in the readme).
NOTE: The included YY-CHR screenshot is of the version that has both Piranha Plants and Venus Fire Traps with stems included.
