Worms?

[Dusty Rhodes]

It's no good Dusty - you're not going to worm your way out of this one...

I honestly thought that must be a Photoshopped picture, must have been absolutely optimum conditions for reproduction, and then a Malthusian crash in availability of food.
You don't by any chance have the same garden designer as Willie Wonka and the Chocolate Factory, do you newbi ?

No need for Photoshopping Sno. There are sandworms living in the Sands of Forvie. I have a photo of one in my album...right next to my photo of Nessie

Worms usually move away when the conditions change. It could be their environment is getting to wet, or their environment is becoming to acidic, or as mentioned earlier they have run out of food.
