When I was done doing quests I went to check on my plants. When I came back there was a pixie on my laugh-o-dill. It said my plant liked it but it was making my plant (which was not mature yet) grow slower. I was wondering how the pixie got there and why it has stunted my plants growth.
It speeds your plant's growth, it doesn't slow it. Some plants attract Pixies naturally, they prevent bugs on that plant and speed up the growth of other plants in the area.
