It was a picture book but from what I recall very scary.
My memory of the story is very very scant
What i do remember is some red coloured goblinny type naked long nosed things..who swarmed ....they ran at night in huge groups through long swishy grass
The story was something like 'Through the long grass ran the 'whatever these things are called''
they came night by night
I would be really grateful of any input as this bugs me and i would love to find it..
Thanks
