You can take a look at the image below to get a good idea of what I mean. Notice how the drake's head is partially below the floor in the second image, while a tile is missing from its tail section in the first. In the third, its left leg is cut off midway.
It seems to be only one tile on the drake's overall graphic that's causing the issue.

Also, I found a photo of the "Ridable Drake" graphic from OSI, which is a 12th year veteran reward, and it doesn't seem to have the same problem. It does look like maybe the graphic is slightly elevated, though... maybe they had the same issue and modified it a little?
