“Marines, coming in from every angle, we need a way out, but how, we need a way” then, the lid from the sewer flied past his face, interrupting his train of thought but giving him the idea he was looking for. “The sewers, it's the only way out, have to take only the important things then, no way the cart fits in there” taking out two suitcases from a secret compartment on his cart he moved the lid next to the hole and took out a flash bomb and threw it at Natsu, then some smoke grenades that he threw all over the battlefield creating a heavy smoke field. making his way straight to Sammy he looked him straight on and with a very serious face he said
“Sammy, I know you want her as a navigator and I butted in the fight but, we don't have much time, we have a minute at most to escape, that manhole is our only way out and the smokescreen won't last long, we have to bail for now, regroup and plan this through.” grabbing him and dragging him towards the manhole “Trust me, I'll even buy you some meat for this but we need to move now!” 
Both of them now next to the manhole, Griff threw his two suitcases in there and turned a crank on his cart. “When we enter the manhole, use this to light your way” Griff gave Sammy a toy soldier shaped lamp “just spark the tip of the mouth and a flame should lit, with your powers it should be easy” (the toy is esentially a fire breather imitation toy, when lighted it moves it's feet in dance and flame comes out his mouth, a dial on it's back regulates the intensity of the flame) 
Griff entered the manhole and lifted the two suitcases and looked at Sammy “You coming, captain?” 
Meanwhile, the cart was now rigged to blow, activating all the noise bombs, fireworks and weird trinkets inside, all but the gunpowder flower, which was in the suitcase, along with Griff's “savings”.
