MR. PINCHY WISHES
# Mr. Pinchy's: 20
So far, it looks like there is an equal change of getting any of the 5 wishes. However, these results should still be taken with a grain of salt considering the small number of Mr. Pinchy's & Wishes. My guess is that people only notice the pet whenever they don't have it (myself included) and think the chance of getting it is lower than the other wishes. So far, though, it looks equally random (although that won't stop anyone from /crying over the lack of a pet...) Keep posting your results, though!
