Interesting, but not really working for me. I see collectibles sometimes after dropping kids on various purple plants (since everyone has a different favorite), but it doesn't work for me repeatedly.

Thinking this is completely coincidence -- if collectibles tend to appear every 5-10 seconds, and you are dropping kids on purple plants once every 5 seconds, it will seem like the two are related even if they aren't.

Another test -- pick another random spot in the village and see if dropping kids there seems to make collectibles appear.

(I like Borg's idea, but don't have 30 free minutes to spare at the moment ).
