There's an old film i remember but i don't know what it's called it was about fairies?

I think it had nimph in it i dont know, there was a bat which kept crashing into things, and there was workmen in the beginning coming to chop down the forest and one of them got shrunk and met this girl fairy - the main character - and she saves him from getting chopped by a tree,after that she meets her gang again, there's a ginger guy fairy who take severyoine on grhoppers and they fly through the forest there's also a scene where they're on ice. Her gran grows the heart of the forest and leaves it up to her at the end. I can remember at the start there were red X's on the trees going to get chopped down and the fairies didnt know what it meant. another scene is where the man (that was shrunk) had every fairy dancin to his cette tape, the bad guy in the film is the black smoke that's killing the forest. i know this sounds cheesy but i loved this film sooooo much please help x Thank you :)
