OK so let's go for . . . . . ANIMAL

[BtD] No. I thought that might be too predictable. :o)

Well done Boolbar (bit of a geezer) :-). I'm determined to get the answer one day soon. It keeps happening just as I'm on the verge of nailing it - but get called away for something trivial, like earning a living.

whereas migratory birds are incontinent.

[Chalky] No. But keep guessing. This might be your lucky day.
[Inkspot] It originated from one continent.

Even a bee can cross continents

[rab] Technically, no. Physically yes.
[Raak] No.
[Kayl] No.
[Chalky] No.
[BtD] No.
[Inkspot] No.

[rab] Yes.
By heck! It can be difficult deciding what the answers should be sometimes. But nice to see how people can go along the wrong tangent.

[Chalky] No.

I'm off home now. I might be able to check in later, otherwise it will be 09:00 GMT tomorrow before I'm back.

I don't think so, since that would have two legs... so...

Since there is a film about that one out...

[Chalky] I wouldn't call it an animal product no.
[rab] (a) No. (b) A copy might be but I don't know to be sure.
[Ibid] (a) Yes. (b) No.
[Inkspot] It did cease to 'exist' in the last 50 years but I guess it is also still alive. (Is this a clue?)
[Tuj] No.

As in kangeroos - Australia
Penguin - Antartica
I know its a blind alley, but I'm a bit lost at the moment.

ie;Shep the dog / Shergar

In which case that narrows it down to mere 7,098,764,098,764¹⁰ :o)

Dead but still alive?

A good nights sleep, a disease that was eradicated but still alive in labs, are there any others?

Hmmm, perhaps I better fill in a few gaps.
[Inkspot 1] 'It' is associated with one country - but didn't always stay there. 'It' might be there now, or spread around more than one country - I don't know 'its' exact whereabouts at this moment.
[Inkspot 2] 'It' has a name and I'd be surprised if anyone here had not heard of 'it'.
[BtD 1] No.
[BtD 2] No.
[Raak] No. But at least someone is starting to think around the "not 2 legs" bit.
[Chalky] No.
[Inkspot 3] No.

I think it is the existence thing that may cause confusion (it confuses me). 'It' no longer exists in a similar way to the last MC pilg not existing any more.
