we are talking grass that will wrap around your feet in seconds , vines that will rip your limbs from you in even less time , orchids that will dissolve your flesh until all that is left is a strange exotic smell , trees that will collapse on to you , crushing you to absorbable pulp under their great weight , bugs that will skin you alive , butterflies that will cling to your face and suck out your brains , worms that will bore through your flesh like acid through butter .
