Dennis and his faithful hound Gnasher are out to make every day as much fun as possible, but their adventures often lead them into trouble. A shadowy government agency have managed to make a copy of Gnasher's legendary teeth in order to develop The Gnashinator - a top secret super weapon of epic proportions. But they have bitten off more than they can chew - and soon Beanotown is in tatters... there's only one master of Gnasher's gnashers - and that's Gnasher himself.
