Arachnid!!!!s are insect enemies in Mother 3, located in the attic of Club Titiboo during Chapter 4 . First encountered by Lucas and Boney, Arachnid!!!!s are the stronger and poisonous counterpart of the Arachnid! encountered back in Chapter 2 at Osohe Castle.
Its appearance is simply a dark blue-purple shaded 'Arachnid!' It appears to be quite fast and aggressive in the overworld. It runs away from Lucas and co. once they've beat the venue's boss or reached level 99. Their Battle Memory examine text is, "It has an incredible three, no, four exclamation marks in its name. That's just the kind of spider it is."
During battle, Arachnid!!!!s have a relatively decent amount of HP, easy enough for it to be defeated in less than 3 turns. They can travel in cohorts consisting the Elder Batty and Greedier Mouse. It is advised to bring healing foods such as Nut Bread and Hot Spring Eggs. Arachnid!!!!s can deal moderate damage, possibly attack twice in one turn, and most notoriously, poisons one of Lucas and co. to an often-to-rare rate. Once defeated, it drops an Antidote. It is weak against Bug Spray, explosions, and Lucas's PK Love.
