The first storyline completed after just 66 black and white pages, and has now been published in colour as a book. A second started in mid- to late-2014, this time in colour.
Cochlea & Eustachia contains examples of:
- Antenna Adjusting: A variation. In order to make a radio work, Fronky (see Shout-Out below) attaches antenna leads to a fork and sticks it into one of the girls' heads while the other strains to hold the set.
- Apocalypse How: A hint of this in the field of bones stretching to the horizon outside the building.
- Bag of Holding: The narrow-necked bottle from which Cochlea pours hundreds of small objects in the hope of finding something useful.
- Body Horror: After Cochlea has finished stapling(!) what's left of their dismembered bodies back together, Eustachia and the third girl end up conjoined with limbs all over the place, like a bizarre human starfish. They don't seem too happy with the arrangement, but Cochlea doesn't see any problem with it, and soon finds a good use for their new shape.
- Contrived Coincidence: At the end of the first story, Cochlea finds a paddle-powered raft that's worked by the same kind of see-saw handles as a rail handcart. It just so happens, those handles are exactly the right shape for the now-conjoined Eustachia and third girl to operate.
- Dada Comics: Although comedy isn't a major feature of this webcomic, there are several amusing moments and visual puns.
- A Date with Rosie Palms: In the color story, one of the girls gets aroused by a hardware catalogue.
- Fanservice: Cochlea and Eustachia's dress code. Skimpy at best.
- Fan Disservice: Eustachia mostly naked, but also dismembered and eviscerated. Ew. That's even before Cochlea starts stapling her guts back together... and getting all the bits in the wrong order.
- No Plot? No Problem!: The author has stated that the Cochlea & Eustachia storyline will be "completely unencumbered by tempo, character development, plot, or logic."
- Mind Screw: Trying to figure out where the story is going, or even if there is a plot. (For what it's worth, the author claims there isn't.)
- Recursive Reality: Certain objects inside the building, including one of the heroines, contain entire living rooms—complete with furniture and occupants.
- Reset Button: The second story starts with both girls looking the way they normally do, ignoring Eustachia's bizarre fate at the end of the first.
- Shout-Out: In the second story there's an odd character who's referred to at one point as "Fronky". This may well be a reference to "Fronkensteen".
- Squick: See Fan Disservice above.
- Surrealism: The building being explored by the female protagonists is filled with random (and usually very strange) objects, and has... unusual spatial properties.
