The gang get lost in the woods and stumble into the Land of Lost Things, where Gnasher gets dognapped by a Gnashersaurus Rex which has lost its beloved egg. To save Gnasher they have to rely on Pieface logic to reunite the G-Rex with its egg before Walter makes a record-breaking giant omelette with it.
