Here, I have created a falling pinecone image, that will replace the stalactite in the forest world. I have not made an image for when it hits the ground yet. I hope you enjoy them!
Clever idea! It may need a little bit work to make it suit the SuperTux style. Here is an old PR on Github for a forest equivalent of stalactite: https://github.com/SuperTux/supertux/pull/367
Thanks. mteufel and I discussed this in the IRC a few weeks ago. I was using a pen and paper at the time, maybe soon I'll get a drawing tablet. And I've seen that pull request and a hanging ball isn't a very creative idea.
