I love this one.
It is a highly intelligent mammal (although it looks very foolish...) with an elephant-like trunk, a VERY thin neck and a fat body with two very strong legs.
It was drawn with graphit and coloured with colour pencils. But in this picture you can see how cruel classmates can be: they tried to destroy the picture with a ruler, you can still see the traces...!!
