BeebleBear

From Conbledegook

A type of teddy bear with three arms and two heads, typically sold in the dealers' room by ZZ9 Plural Z Alpha, the official Hitchhiker's Guide to the Galaxy Appreciation Society. It is a reference to an alien called Zaphod Beeblebrox who is a character in the Hitchhiker's stories.

Orbital 2008 has a special membership class just for Beeblebears that is basically a toy membership which costs 42 pence extra to account for the extra appendages.
