Sling chunks of mud around for the greener good!

Battala Verde (or Green Battle) is a fight that sprouts green spaces. A dreamy mess of game, Urbanarborlismo got together in hopes of creating new green spaces on their coasts of the Mediterranean.

The optimum 'battlefield', a carpark-like slab of concrete in need of life; 'ammunition', of green mud slops laden with seeds; and a few rules, like fighting in groups permitted, and one idol per group.

The seeds of resistant plants won't need a lot of care post-battle and should sprout within 2-3 weeks.

The group also churns out the likes of vertical gardens, tree houses and a whole bunch of other good-looking stuff my Spanish isn't good enough for, check it.
