Jean,
The list of wonderful toys I've let go of and/or abused is long and depressing. I salute your canny hoarding.
Vis the "Dragon's Domain" ceph-monster, I've run a a search for the thing and come across a number of
Space 1999 forums and nostalgia sites. The consensus opinion is that "Dragon's Domain" was easily one of the best episodes, if not the best. Further, the response people had to that monster seems to have been one of generalized terror. "That thing scared the crap/****/bejeezus/hell/**** out of me when I was five" is the common claim. My well-meaning parents tried to reassure me that the Dragon was only a special effect, produced by the artful manipulation of "blankets." I went to bed, frightened of monsters
and bed sheets.
