Why do the various bad guys in the series have presents anyway? That seems kinda silly to me, for a crow to have a cookie, or for a mouse to have a bomb. Where did they get these?

Well this may be an exceptionally short little tidbit, but I thought I'd share my thoughts. That's kind of a difficult one, where do these creatures get presents? I mean, I guess we can ignore the aliens having presents because, well, they're aliens they can basically get away with anything and we couldn't really question it, huh? The contents of the presents are also kind of strange. I do kind of get why a crow would have a cookie because I have seen crows and other birds picking up food off the ground (although I've never seen one pick up an entire cookie). Then there's the presents containing bombs and such. I've decided that since these games are usually quite silly in ways such as this, I will give a silly explanation. My explanation is that someone somewhere was having a birthday party and had many gifts that were filled with everything from cookies to lethal substances and all the games' enemies raided the party and stole the gifts. Some of these gifts also ended up scattered around the worlds. Well that may sound just completely stupid, but that's what I think anyway. Thank you for taking the time to read this.
