Which is scarier, tentacle or random legs?
I guess the "active imagination" is about that tentacle which shows Nightmare has watched too much hentai or something. But little does the tentacle monster know, Roxanne is even MORE of a Lovecraftian nightmare given the non-euclidean geometry going on with her legs and body.
Incidentally, I had to look up who this character is. She's only had 5 appearances in the comics??? It's so weird she was in a swimsuit special. I guess she was either really popular for a very short period of time or they were trying to push her hard.

"Never one to content himself with daydreams, Nightmare cooks up more than a coconut cooler while his ladylove Roxanne puts up with his "active" imagination."
