Rain on Your Parade

The level is called Museum, the one with the painting you had to steal; it’s in the upper center of the map. Go there in NG+ (after finishing the game). Break open the wall in the top left with the bowling ball (snow helps). This time you don’t need the Mona Clouda, just use tornado going around the edge of the main room to grab all the other paintings off the walls. Drag them to the opening you made and throw them in. You will probably drop a few on the way so just clean them up and when the tracker shows you have them all the achievement will pop and you can quit out of the level.

This can only be completed on New Game Plus. Load the Museum level and use your tornado to grab all of the paintings off of the wall. Carry them to the end of the level and throw them out of the museum. Don't worry about the painting in the glass, that is your main objective and we don't need it.

You need to play in NG+ in order to get this achievement. Very easy.
