I created this picture in Gimp. First I found this picture on twitter while searching Northquad.
I used the magic wand to delete the picture of swimmers added. Then copied and paste pieces of the water to fill the space.
I then open up a picture of phineas bedroom and cropped out the bed, then pasted it into the new picture. I opened up Phineas and added him similar to the bed. Then used the text to say where is perry.
