Using the MrBeast Lab Mutators Stealth Panther is easy. First, pour the mutation liquid into the chamber. Then, press the fingerprint scanner. Wait and watch as your Stealth Panther is revealed and comes to life. Make sure to keep the mutation liquid away from eyes and mouth. If it spills, clean it up right away with a damp cloth. When not in use, store the action figure in a cool, dry place to prevent damage. Enjoy your new MrBeast - inspired toy and collect all three Mutators!
