Chumbley

Chumblies were the nickname Vicki gave to the Rills' small robot servants, named so after their wobbling movements. One of the tasks the Rills gave them was to deliver messages. They attempted to deliver one to the Drahvins multiple times but were fired at. They resisted gunfire by deactivating and then reactivated when the firing stopped. They were made up of circular rings that grew smaller towards the top. The rings could all fold down into each other in protection. (DW: Galaxy 4)
