Apparently this little guy with the shake is evil, so someone has to take care of em. Hey- who's that looming above the guy?
(I almost didn't have enough time to draw and post this-)

Lore: Nightmare bubbles occasionally float around the Dead Zone to Dusclipse Woods border, and in the deeper parts of the Dead Zone. They will instantly ruin anyone's day by trapping them and inducing nightmarish hallucinations. They may not even feel the bubble around them if it is immersive enough, making escape even more difficult. The fear may be the biggest reason they can't escape the bubbles. If the large tanking to the victim's sanity isn't enough, then the hallucinations themselves may kill them. Yep, these are one of the few bubble types that can kill!
