The 6a Walter Peck features multiple points of articulation, and is accompanied by the ghostbustersa containment Unit. Representing the interests of the EPA, the perpetually insipid Peck visits the ghostbusters headquarters and immediately rankles in the company of the ectoplasm-spattered Peter Venkman; Peck demands to see the storage facility and is refused by Venkman. The vengeful Peck later returns with a court order and succeeds in having the containment grid shut down, which results in a deluge of ghosts released en masse against an unprepared New York city.
