Voodoo

I may need a bit of witchcraft over the next few weeks - but that doesn't really explain my other half bringing this back to me from his trip to New Orleans. Luckily it comes with a white pin, which apparently means you can use it to bestow good luck rather than bad. All I need now is a couple of chicken feet and a frog?
(Does drowning a massive banana slug yesterday count towards witch behaviour? I feel bad about it, but I had to, it had eaten most of my broad beans. To be honest I'm still rather torn about my murderous action).
