The Smurf Masher is a vehicle created by Gargamel in the cartoon show episode "The Smurfbox Derby" after he had witnessed the Smurfs in their new smurfmobiles. The invention resembles a primitive medieval version of a steamroller, and its purpose is to smash the Smurfs flat. It is powered by a treadmill operated by Bigmouth, who is lured to chasing after a pot of stew.
