First known celebrity voice (Cassandra Peterson - Elvira) especially recorded for the machine.
Approximately 4,000 units were produced.
Elvira is known to be a little risque. As a precautionary measure, Elivra games were shipped with a small, black lingerie 'decal', to be placed over ELVIRA's plunging cleavage on the backglass. The software included a similar option to tone down the quotes. This was the 'Rated-G' option, intended to 'Protect the eyes and ears of the little Party Monsters'.
The slingshot/outlane plastics are bordered by long bones. The 'broken' bones on these plastics are an 'inside joke' about Dennis Nordman's motorcycle accident, which occurred during the development of Elvira. In fact, Dennis Nordman broke many, many bones in the accident and basically designed Elvira from a hospital bed!
The graphic on the right side of the game near the pizza passage with the monster carrying a shitload of pizza boxes. One of the pizza boxes is named 'Pinball Pete's', and this is the name of the Arcade that Tim Arnold used to own (and subsequently sold to his brother) in Michigan. Guess someone working on the game wanted to point out Tim and his efforts in pinball.
