PLNK-series power droid/Legends

"Plunk. Plunk."

- Plunk droid

Plunk droids were four-legged power droids that served the Confederacy of Independent Systems during the Clone Wars, for which their roles included the counting of freighters that passed through the Separatist blockade of the Gwori system; as well as for the Grand Army of the Republic, working aboard Venator-class Star Destroyers and providing power for listening posts. They spoke a form of droidspeak similar to Gonkian and could function as containment units for liquid tibanna.

Characteristics
Plunk droids came in colors from dark green to gray and brown and had four legs, as opposed to the two of the GNK series, although they spoke a form of droidspeak similar to Gonkian, saying "plunk" as they shuffled about. The units had hoses running from their left sides to nozzles holstered on their backs. As part of their power-allocation duties, these units could carry liquid tibanna. Three such plunk droids used as tibanna tanks could supply enough power for a Republic listening post and also enough to destroy the post in case of insurgency. In the service of the Confederacy of Independent Systems, plunk droids were thought to have some defective circuits, leading to miscalculation.

History
"One of those plunk droids probably miscounted again. Their circuits are defective."

- A B1 battle droid

Plunk droids were in the service of the Separatists during the Clone Wars, where they counted freighters passing through the blockade of the Gwori system to the Gwori Shipyards. When B1 battle droids noticed one too many freighters in a convoy, they dismissed it as a calculation error made by the plunk droids, whom they claimed possessed defective circuits.

The droids also served aboard the Venator-class Star Destroyer Resolute in the Open Circle Fleet of the Grand Army of the Republic during the same period, and could be seen shuffling about the hangar bay of the vessel, where BTL-B Y-wing bombers, LAAT/i gunships, Delta-7B interceptors, and V-19 Torrent starfighters were housed.

Three more plunk droids, containing liquid tibanna, served as the power source for the GAR listening post on the Rishi moon, which was used to monitor a portion of the Outer Rim Territories for possible invasion by the Confederacy of Independent Systems. When Separatist droid commandos captured the station, the clone troopers aboard decided it was necessary to destroy the installation and therefore rounded up the three plunk units and wired them together in order to detonate them using a thermal charge. When the remote detonator failed to sync up with the charge, the clone Hevy sacrificed himself to manually trigger the device, destroying the three plunk droids along with the installation.

Behind the scenes
Plunk droids were created for the 2008 CGI television series Star Wars: The Clone Wars and first appeared in the background of the episode "Shadow of Malevolence," which aired on October 10. The droids were first named in the StarWars.com episode guide for "Shadow of Malevolence." They later had a more active role in the October 24 episode, "Rookies," and could be seen once again ambling around a hangar bay in "Jedi Crash." The appearance of plunk droids is very similar to that of the GNK and EG-6 droids of the original Star Wars trilogy.
