WALL-E is a cartoon about a small, mobile trash or garbage compactor alone on Earth. The compacting machine has the words WALL-E written on its side. This little compacting machine spends every day compacting trash and using blocks of trash to build large, building-like structures. There are thousands of these tall buildings of trash everywhere built by this little compactor. Earth is completely covered by piles of trash and tall buildings made from trash. It must have taken this little machine hundreds of years to build all the structures.
