The first photo shows the new version of the Monkey pattern, available in Fuzzy Knits and on its own. The arms and legs have been changed slightly, and the overalls have been redesigned.

Although the faces look different, this part has not been changed in the new pattern. The difference in appearance is due to using a heavy worsted weight yarn for the older toy (red overalls) and a light worsted weight yarn for the new toy (blue overalls)

The other photos show the older version of the Monkey pattern, which is no longer available.
