I am trying to remember the name of a fiction book about a boy that could manipulate plants just by whistling. I think it's a bit of an older book, but I can't seem to find it by searching for those terms. If it helps at all I think the title had something about green in it, but I can't be certain. Does anyone have any idea what it is?
I seem to recall that the book was probably close to 20 years old when I read it and that was nearly 10-12 years ago. The boy first realized he could manipulate plants by using a toy whistle and moved on to being able to make the noises to control the plants with his tongue. I remember that there was some kind of conflict with bad people and he used his ability to fight them and I think it was in a jungle. I think he made one of the bad guys bite off his own tongue by hitting him with a vine. It was in English and a soft cover I believe.
