These things have one thing in common: They have all taken WAY too many performance enhancing drugs. You may use any of these buffed things for Scratch projects, or pfps, or anything else you see it ift for. If you want to know how I did this, The main thing is the Cat1 body and front leg. Then, you make it the same color and size as the limb you want to replace. Copy and paste does the rest.
Special thanks to @MidnightTheKitty for sparking inspiration in one of his projects that he showed me.
