A flumph resembles a pallid disk trailing dozens of writhing tentacles and hollow, needle-sharp spikes, almost like a flattened jellyfish. Its pale skin is nearly transparent in direct sunlight, and atop its domed body stand two eyestalks holding unblinking eyes with dark, horizontal pupils like those of a goat. Normally reaching up to 3 feet in diameter, the flumph weighs only 15 pounds, with most of the weight accounted for by its rigid spikes and tough tentacles. The flumph's tentacles grow slightly longer than the width of its body, allowing it to reach entirely across its own width. These tentacles are as agile as human fingers, and when used in groups can manipulate objects as easily as human hands do.
