Volcano

At the bottom, that is a blue mountain range, with the tallest mountain on the left being a volcano. All the red around it is hot lava, and the blue dots are people who melted in the hot lava.
The thing in the middle with a smiley face is a humpback whale (the lines coming out of the top of it are not a part of it).
The top left is a slide.
The rest is doodling that Chip contributed to as well.
