 Tiki's historical basis with drinks such as the Zombie and Corpse Reviver, along with the use of early skull-shaped and shrunken-head mugs, became a catalyst for more overt "monster"-themed mugs.In a similar fashion, Tiki's link to Atomic cocktails and drinks such as the Test Pilot, Astronaut and Space Needle eventually led to mugs in the shape of rocket ships and early science fiction robots with names such as "Tron the Beachcomber".As aspects of tiki culture became more mainstream, virtually any uniquely styled ceramic mug began being labeled as a "tiki" mug, which saw some pushback among purists.
