Do you know Toad in Super Mario Run? You may well have seen the character even without playing the game.
Apparently the big question is: is that mushroom-shaped and coloured headgear on the character’s head, or is that its head? This is the kind of thing that gamers ponder over - like a deep philosophical inquiry.
Stalker neither knows, nor cares; but as it is mushroom related, it falls within the scope of interest.
