K-Dog is a dolphin, while by nature he should be a free mammal, swimming in the oceans and enjoying his life, instead he's been given a s*!t task: he must look for mines and mark them!

You thought those dolphins in the dolphinaria look sad? How sad is to be considered good in this terrible task because "unlike robots, the dolphins do not run out of power, nor do they go missing or have problems communicating from the sea bed"?
