The title of this article is conjectural; an official name for the article's subject has not been found, so it has been given a fitting title by editors. If an official name appears, it is requested that the article will be moved to the correct name.
An Arachno Snifit is a large, black and red-legged type of spider which, judging from its similar facial features to them as well as the similar name, is a type of Snifit.
In The Super Mario Bros. Super Show! episode "Count Koopula", Mario, Luigi, Toad and Princess Toadstool, after jumping down a laundry chute and being deposited in Count Koopula's basement, find themselves menaced by several Arachno Snifits. Before these Arachno Snifits can attack, Princess Toadstool manages to scare them away using a fireball-spitting Magic Piranha Plant; after being hit by a fireball spat by this Magic Piranha Plant, an Arachno Snifit explodes in a manner similar to a balloon.
Any other Arachno Snifits inhabiting the castle were presumably crushed when it collapsed after Count Koopula's defeat.
