Spock Hopper Dianetics Vulcan Moon

Or it could be a Space Hopper on the Vulcan's palm. 

I wonder if Dr Spock was a Dianeticist?

Dianetics has always had an image of a volcano on the cover, any edition I've seen. Volcano,  Vulkano, Vulkan, one who takes the teachings of the volcanic one with them. Vulkan Krakan, Kraken.

'Dianetics Commercial' 

Also the creatures in V may have been Dianeticists, using Dianetics as an euphemism for Scientology, with Diane/Diana/Moon worship.
