Dialogue >> Greg Heffley is based on Jeff Kinney's main character in Diary of a Wimpy Kid. You help him try to find his little brother, Manny, in Wimpy Wonderland Island and help him get his $20 back on Wimpy Boardwalk Island. Greg's shirt originally was going to be yellow, but for some reason it was white. Greg did not have color in Wimpy Wonderland Island, but had color In Wimpy Boardwalk Island. He was also featured in the room which promotes his next book "The Third Wheel". The user can dance with him there after.
