(Hero - Rogue) in Heroes 4

But still, the developers made a mistake (in terms of appearance) when creating the thief heroes. How can a cow steal art right under the nose of Dungeon?

I imagined this comical situation :D I have two options: either this cow is magical (and enchanted to overcome its clumsiness), or it's a half-cow (like a centaur), only with a cow's head and a human body (probably the result of a terrible curse, just like their neighbors in the castle, the bald Chaos women).
