A humanoid crocodile who runs the pub in Dijabringabeeralong, he wears shorts quite possibly unique in the world, on account of his species. This calls for a tailor who can accommodate very short legs and a massive reptilian tail.
He takes quite a shine to Rinso and even gives him a few free beers, complimenting Rinso on his wizardly abilities (actually Trickster working to protect him from harm) and wistfully remarks: "wish I could do that, mate". Considering that elsewhere on the Disc there is such an entity as Offler, the Crocodile-headed God who can do all this and more, this speaks volumes for how long XXXX has been cut off from the rest of the Discworld.
A lot of the drinkers in the pub are actually humanoid animals. Considering that elsewhere on the disc (Genua) these have been created by Lily Weatherwax and are somewhere on the far side of insane, (or else are the insane animal-headed Gods of Djelibeybi), it's interesting to ponder on how well-adjusted they are by comparison. Nothing is said on how they came into being, though.
