This is a skill point.
After you have gotten the helicopter upgrade for clank, exit Al's shop and continue along the level until you reach the lift, go up, kill the enemies and go up the second lift. Once at the top of that lift, go left and onto the ledge, look down and you will see Al's shop with the statue of him on the roof, jump down using the helicopter upgrade to guide yourself onto the roof. Now just simply stand under the statue, Ratchet will pull a slightly funny pose and the trophy and a skill point with unlock shortly afterwards.
This is the first possible trophy to obtain in this game.
