The tar monster from Scooby Doo, which appears in both the classic cartoon and the second live action movie (or so the internet tells me).
A request that I felt fit the season, so I went ahead and gave it a shot fairly quickly, compared to my usual request turnaround time.
IL_v1: Functional, but a bit finicky, especially about the weight of monster boy and how much of a neck it gives the monster.
Main: TarMnstrSD, dripping, black goo, huge eye, (monster boy:0.5)
Cartoon version: green eye, no pupils,
2004 movie version: blue eye,
