King Koopa is at his wit’s end. Despite having an almost unlimited supply of Goombas, tanks, naval vessels, and an air force, it seems that ridding the Mushroom Kingdom of a pudgy plumber has proved more difficult than planned. The great Koopa has now turned to the power of advertising to gain more support for his cause.

In a set of emotionally-charged propaganda posters, Bowser asks the question, “The Koopa are fighting. Why aren’t you?” and calls for residents of Mushroom Kingdom to join the great Koopa cause. See the set of posters after the jump.

The posters are designed by Fro, a graphic designer from Los Angeles, USA.
