A quick animation I made in 3 hours... Keys: 1 = More ripples... 2 = Why aren't the trees burning down? 3 = The lava is green! 4 = What in the world!?! 5 = I think it's broken??? Yeah, it's broken.
Most of the lava script by @Ctrl-Alt-Llama, that said I did edit it by taking out mouse pointer commands and adding things like number and colour commands. You can check his project out here: https://scratch.mit.edu/projects/215446860
