It seems that the 'floor is lava' game (game is to not touch the floor, the children must get around by climbing on furniture instead) is developed by most children.
My question is how it is so many children know this exact same game.
One argument would be that it is learned socially like many other children's games - for example 'Enny meeny miny moe' is another commonplace game - that is clearly learned, rather than developed independently.
On the other hand, it could be that 'the floor is lava' is a product of innate play (like play fighting, or running around) and easy imagination.
Is there any research on how this game is developed/learned by children?
