12/23 HERE'S A BETTER CHEAT SHEET!
UPDATE 12/2- If anyone has a full set of the figures in-hand that they can use to
perfect this chart, by all means do it. I did this by eye-balling
photos of the dot patterns, so it's not exact.
PLEASE NOTE: The gorilla apparently does not have dots, but instead is a
"weird melted look." Not sure what that means, but I guess
you can distinguish it that way.
Based on THIS.
The bags have unique patters of raised dots along the bottom. I tried to reproduce the pattern the best I could tell from the pictures.
The Indian Chief and Samurai have very similar dot patters. I expect those to be the hardest to identify in-store.
