Topaz Everett, transformed into a crux in the capital wastes, finds her new form to be advantageous for locating the Vault Tec Bobbleheads, which she proudly displays in her home in Megaton. The lack of technology means she is unable to return to her feline form, until she finds Rivet City, where they supposedly have the equipment she needs to become feline again.

The bobbleheads are so rare! You can get transformed anytime. :) Those things... No one else in the wastes has a whole set!

Though apparently de-cruxing herself is a lesser priority than her bobblehead collection - unless she's yet to get the Science one.
