Mini/Harry Potter

A mini-Aragog, also known as a mini-Acromantula, is a miniature version of a giant spider from the Harry Potter series. This type of mini guards the Hogwarts Fanfiction Academy and is one of the few minis to have the power of speech. They hiss a lot and talk like Gollum. Unlike mini-Balrogs, they are partial to bouillabaisse rather than raw eggs and bacon, but will still eat the unwary fangirl or Sue.

Note: Minis are usually based on a species, not an individual, but Meir Brin wrote "The Hogwarts Fanfiction Academy" when only the first four novels had been published, so she did not know that Aragog and his kin are called Acromantula.

The mini-Aragogs are responsible for the manufacture of Bleeprin and its primary derivatives, Bleepto-Dismal and Bleepka.

An old list of mini-Aragogs (last updated in 2004) is available at the archived website of HFA's creator: Meir Brin's Masses of Mini-Aragog Minions.

Canon Origin
Aragog is a giant spider that Rubeus Hagrid raised from an egg during his third year at Hogwarts. When Tom Riddle framed Hagrid for opening the Chamber of Secrets and setting a monster on the school, he released Aragog into the Forbidden Forest. There, Aragog grew to be the size of a small elephant and had many carthorse-sized offspring with his wife, Mosag.

Harry and Ron encountered Aragog approximately 50 years later, old, graying, and blind, after taking Hagrid's hint, "follow the spiders," in their attempts to investigate the cause of a mysterious series of petrifications during their second year. Although Aragog himself would never harm a human and answered the boys' questions out of respect for Hagrid, he would not prevent his children from eating the "fresh meat" that had wandered so willingly into their midst. Harry and Ron were only saved by the intervention of the feral Ford Anglia formerly owned by Mr. Weasley.

In Fantastic Beasts and Where to Find Them, Acromantulas are classified as XXXXX, "known wizard killer / impossible to train or domesticate" (unless you're Hagrid, apparently). The entry notes that they have near-human intelligence and were probably bred by wizards to guard wizard dwellings or treasure, since beasts capable of human speech are rarely self-taught.
