"Most [hill trolls] enjoy removing all flesh from the victim, then eating the internal organs. They are very selective, and will leave all muscle untouched, but eat the internal organs instead. Almost always, hill trolls save the brain for last, which they consider a delicacy; it takes as long as an hour to eat. Although hill trolls crave the cortex and the surrounding cerebrospinal fluid, they savor the taste of the limbic system, most specifically the amygdala, basal ganglia, and hippocampus. Oddly, they always reject the thalamus, but devour the hypothalamus. While tasting the limbic system, hill trolls will become erect or wet with sexual excitement as well."
