This is a lost artifact, known only through ancient stories of long-deceased ancestors, and has not been discovered in Ur. Perhaps the most useless piece of clothing in existence, this pair of trousers - pair is possibly the wrong word for something with 16 legs - this Multiplicity of Trouser was created by a loyal Humbabarian as a gift for a passing caterpillar, in order to cover his modesty. However, since caterpillars famously have no modesty (or, in fact, shame) not a single trouser in this multiplicitous garmental gathering have even been worn.
