The Snake-Mountain stands are much cooler in person and help differentiate the "Evil Warriors" section of my display. I only used the extra "rock" piece once or twice as it just doesn't look right in many of the peg holes.
Slush Head is very cool. I'm tempted to add water but fearing loss of paint on the head, mold, or leakage, I'm holding off for now.
Stinkor is great! Deco is good. Smell is just right. But the forearms as they are assembled are grotesque. I am in the process of swapping them now. It is very simple if anyone is feeling too intimidated to correct their own. In fact, I will post a brief photo tutorial on my blog soon to help others who want to fix their figure.
