Instructed to “follow the spiders” by Hagrid in Harry Potter and the Chamber of Secrets, Harry and Ron venture into the Forbidden Forest after dark to try and find the creature attacking Muggle-borns at Hogwarts. Instead, much to Ron’s dismay, they find Aragog, Hagrid’s former pet Acromantula, and his offspring. While many of the spiders featured in the scene were created with CGI, Aragog himself was made by the creature shop using an Aquatronic system of cables pumping water rather than oil-pumping hydraulics. His eighteen-foot back legs were operated by puppeteers, while his front legs were mechanical. Voiced by actor Julian Glover, he is one of the most memorable—and terrifying—creatures in the Harry Potter films.

Worked flat back and forth in rows, spiders creep their way up the scarf in a line with two-stitch cable twists on a background of reverse stockinette. Wrapped stitches form the abdomen, and stitches knit through the back loop make the many legs pop. The length is easy to adjust by adding or removing spider repeats.
