It is a collaboration, with two artists Matt_tieu and Toctoc, which is the most amazing and original that we can admire here !
One of the Duduss Character of Toctoc is riding an ostrich, he is raising his arms like if he was doing rodeo. The ostrich, drawn with treatment, like knows how to do Matt_tieu, is running straight ahead. The two characters are representing as skeletons. This work, drawn with a chalk, is full of details and precision, which add to its beauty.
