I can't decide if I want to watch the Leopard Slugs mating video or if it's going to give me nightmares!

Haha, just watch it. It's fascinating. :)
I even watch and interact with the most terrible animal on the planet - Homo sapiens - from time to time and I am still alive ...

Honestly if I came across that Leopard Slug I would be trying to head off in the opposite direction myself, it's a scary beast that kind of looks like a mobile pickle.

In reality it's the prototype of the next new STEEM Monster. :)
