This is not the one I saw the other day...but there are ants.

Actually, as mentioned before, it looks like there are some others in picnic kits. Don't know if you are looking for the comic book looking kind or real looking. But looks like they can be found here and there on various sites. I was looking for lemonade stand type of items a few weeks ago and bumped into a few, but didn't tag them.

I didn't look, but there could be some ant brushes and you could make your own paper.

Google and looked under "images" to find some ants. When I can't find elements on items I sometimes make my own from images found there. There are some cool looking ones that would certainly work.
