My goal was to upgrade the vintage toy by adding a bit more articulation, detailed and poseable vine tentacles, a mouth to resemble the cartoon, and a detailed paint job. To the face, I added side-burns, a bottom jaw off a Spawn Vertebreaker figure, and sculpted new "red fangs" since the figure's were broken. I added poseable elbows from adjustable faucet parts, attached tentacles from Green Lantern movie Parallax toys (finally found a use for the horrible things!) with the hollow bits filled in, and extra detail sculpted on. I attached an extra tentacle on each side with a ball joint for some extra poseability.
The soft parts of the figure (head, legs, tails) were dyed a darker green so they didn't have to be painted. I tried to minimize the amount of paint on the soft parts so it won't become tacky. The rest of the figure was painted via airbrush to match the dyed parts with Gameworkshop paints and details drybrushed. Aquarium plant branches and model grass were attached for extra detail. I added a bug's eye pattern to his eyes for fun.
