Not an "adult" film, you understand. Just an adult film.

(We now know that this animal is fictional, but not from a book, children's film, or known from an artistic representation...)

[CdM] Film for adults - NO
[Kim] Dino? - NO
So, by a process of elimination....

Building on CdM's summary, if I have this right, the individual animal has never actually existed but is a human construction, represented not in books or artistic representation (which I take to mean painting, drawing, sculpture, etc) and not in any film made for children, adults or teenagers but in some other artistic form; moreover, the species to which the animal belongs is a real species, but the species does not exist in the world today, nor is it what we would call a "dinosaur".

[Kim] Subject of poem? - NO *some chuckles in the audience*
[G3] Trojan Horse? - NO
[CdM] TV - YES *sighs of relief*
The summary is correct, except around the 'species' (and this is my fault). It's probably best to say that the genus is real and current, but this particular creature isn't. After all, it doesn't exist, so has never been classified, so I'm extrapolating here - is it a species or a sub-species - search me. However, I suspect that you would probably think of it as part of an existing species.

(e.g., Flipper the wonder horse, Lassie the bush kangaroo) (I'm assuming not, because otherwise I think INJ would have led with Animal rather than Abstract ... but INJ's original definition did seem to leave the door open for lots of things.)

[CdM] Real Animal played part? NO (or I certainly hope not)
[Phil] Mr Ed? - NO
[Raak] Cartoon? - NO
[Projoy] Particular actor? - NO, not as such *Some muttering in the audience*[Kim] Named after animal? - NO

I'm also going to request a clarification on the classification. Though you have classified this primarily as abstract, does (or did) it still have some physical (presumably vegetable or mineral) existence? (Although maybe that is just a very roundabout way of asking Kim's question for the third time!)

[Raak] Mr Blobby? - NO
[Kim] Puppet? - NO
[CdM] Voiced by well-known actor - NO
[Dujon] - still no
CdM - Some physical existence? - YES *some applause* (but the classification is still correct)

Not a real animal, not a puppet, and not a cartoon. Not many possibilities left.

I am thinking along the lines of something like Pudsey the bear (though not him of course as he begins with P).

Just as an observation, we have nothing indicating that this is a children's show, though I think we are all tending to assume that it is.

[CdM] Gorilla-suited? - N)
[Raak] Invisible? - NO
[Kim] animated? - NO (I don't split hairs in this game)
[Bigsmith] Logo/Mascot - NO
Playschool? - NO
[CdM] Good point, well made.

[Software] Panto pony? - NO (precluded by answer to CdM's previous question)

Not a real animal, not a puppet, not a costumed actor, not invisible, not a cartoon or other animation. We are obviously missing something here but I am drawing a blank.

[CdM] Was the animal seen? - YES (it will become clear)
[irach] birdy? - YES *relieved applause*

[irach] Phoenix? - NO
