Step 1: Look like an uber cute marshmallow baby. Then no one will suspect you.
Step 2: Convince your sister to carry out your evil snowballing schemes.
Step 3: Sweet-talk your Mommy into letting you down on the snow. Look innocent. Wait for the right moment.
Step 4: Fall back quickly when no one is looking... FOCUS, because the next step is tricky.
Step 5: Roll on to your belly and attempt to get a mouthful of this wonderful, mysterious white substance beneath you. CAREFUL! Move quickly before Mommy moves in and enforces her no-fun policies!
If you get caught and all your plans are foiled, don't fret, there's always next time!
