Slugs...

[2sp_]

We get black slugs and brownie coloured slugs in the garden.

I seem to remember that one is a good slug and one is a bad slug (Gastrapods of the Wild West...).

There was a rhyme to remember which was which, but I can't think if it was -

a) if it's brown put it down

or

b) if it's black put it back

Any ideas? (Or am I just havering?)

DON'T google images of slugs.

I may have nightmares tonight.
