A race that has no clan.

No patron because that race abandoned them on the very day they graduated from being clients.

No clients because any Uplift institute would instantly grant their reassignment if a petition was made.

Nobody wants them.

They smell.

They smell bad to all humans and they equally smell bad to the Urs.

The Ahp'Churezz have a basic kangaroo shape, but pouchless and with full sized arms. The tail is a bit like an elephant's trunk and a bit like a scorpion's tail. Highly flexible and able to come forward over the being's head.

The Ahp'Churezz are fuzzy furred all over.

Uplift gave them voices, but they've always had a second sound system. The reason nobody likes them.

Solid waste is processed in the normal manner, but all gasses are filtered out and are then stored in pockets all along the tail.

The end of the tail has its own vocal opening.

And that opening is used quite frequently.

Never developing into anything of importance, perhaps due to their patrons having as little social contact as the institutes allowed, at the end of the 100,000 years of indenture, the patrons basically said "Don't call us--and we certainly won't call you."

For 100,000 years they had thought that the noise and smell that the Ahp'Churezz had made was totally involuntary.

But the Tytlal discovered the truth.

They found a shared interest. The Tytlal tracked down an additional sale Earth had of the entire set of recordings of the Marx Brothers, Abbott & Costello, The Three Stooges, etc. Everything that the Tytlal had bought for themselves.

The Ahp'Churezz had a sense of humor.

Knowing how humor is treated in the Civilization of the Four Galaxies, they kept it hidden.

For 100,000 years they kept their humor secret.

That tail noise isn't involuntary.

It's how they laugh.

For the Ahp'Churezz have a tail full of sound, and furry, signifying nyucking......
