How does this go?
If Scooby gets his mellow mutt costume or his super power inducing scooby snacks from the most recent show then he stomps.
Even without those though Scooby and gang would win in the end. Plus Scooby could always call in Batman, the Globetrotters, or Don Knots for support.
If the scooby gang could stomp so hard then why did they get butchered by Jason Vorhees on that one Robot Chicken episode? Obviously this proves that they're nothing but weak.
