For all three figures, I attached the heads from the 2020 Plasma Series Venkman, Stantz, and Spengler to the bodies of Marvel Legends Black Panther Everett Ross, then replaced their suit coats with bespoke lab coats I made from a shower curtain and repainted their shirts and ties.

All of their equipment -- Dr. Venkman's Panasonic PK-750 Color Video Camera, Quasar Video Cassette Recorder Model VP5410TE, and ES Mk. I PKE Meter, Dr. Stantz's Bacharach 300 Series Sniffer (a modified United Technologies Bacharach Sniffer 300 Combustible Gas Indicator), and Dr. Spengler's stereo headphones connected to a stethoscope and Radio Shack Trs-80 Pocket Computer PC-4 with Radio Shack PC-4 Cassette Interface --is bespoke. I used Polystyrene, painter's tape, beading cord, jeweler's wire, and paper.
