Purple Bubble Tree
The purple bubble tree is the next generation of purple bubbleshrub. Its bark has adapted so well, that it is now completely fire proof. It also is nearly impossible for the climbing sandworm to eat it. The plents, however, have become the trees' prey. Due to the success of its exploding hydrogen seeds, it can kill its own nibbling herbivorous prey. It uses the burnt carcass as fertilizer to help in grow. It has also minimized its fire resistant leaves, so that there is less to burn. This means a slower growth, but this is compensated by the rich soil that it creates.
