I love this! It really was worth watching right to the end - like something from an alien planet, but very beautiful.
I have tried reloacting the snails from my garden but they are like homing snails; you can actually follow the trails up the road and back to the house. Given that they are so attached to their patch of land I have given up and now plant less tasty plants and shrubs and keep everything edible under wraps as much as possible.
I used to keep chickens. They were excellent pest control experts. Trouble is they were expert at demolishing food crops too. After one attack on my herb border we ended up with eggs that had a decidedly minty flavour for about three days.
The moral to the story? Prevention is better than cure
