Not terribly important, but in the episode with West Gackle giving a caribou to East Gackle (To Kill A Caribou), Andy and Danny paint the caribou while it's asleep. About five seconds before they get into the tent to begin, you can see them carrying three buckets of paint - red, green, and yellow. Now, how come when we see the finished product, there are some drawings in PURPLE paint? No combination of paint that they brought would create purple, and they didn't bring any with them. So where'd it come from?
