I think that spdytypr88 was asking if that could be an improvement in VV2 (or VV3???)

i.e. they ignore mushrooms until they are "taught." the first time. Then after that they will pick a mushroom if they are within 5 pixels of one. The next time, 10 pixels, and so on... (or even just increase the range one pixel at a time.) That way they start small, but improve as they gain experience (like researcher's tech points...)
