While these crayfish sound really destructive, do we know if there's any way to control these populations and to stop them from spreading further?

And Michael, now for the utterly worthless bonus points.

Is there any way you can connect this to our fruity theme?

Panelists often are, which is crazy.

Who doesn't like a point?

I should make a star chart, I think.

Stars, there we go.

You'll get a gold star if you can link this to the theme of the devastation of the Alfonso mango crop.

I didn't know that, but did you know that mangoes and crayfish go very well together in a salad?

It's weirdly true.

We've heard before on this show, we've covered the subject of invasives and listeners have sent us these brilliant examples of when eating your invasive species is a really good strategy.

And where I live, we get invasive crayfish in the rivers near my parents and one of the local restaurants has added them to the menu.

I feel like I've had a salad with mango and crayfish in it.

That was really good.

It's a classic.

You can start something in Kenya, Michael.

Okay, maximum points for everyone.

Thank you very much.

And just a reminder that if any of our listeners have any exciting recipes involving invasive species, unexpected at bbc.co.uk is the address for getting in touch with the show.

Talking of which, let's take a moment to see what's in the inbox.
