This comic reimagines the internal structure of the earth, mixing the real geological layers of the planet with fictional ones. Some of the fictional layers are appropriated from the layers of other objects that have cross-sectional diagrams, such as the layers of a piece of fruit, an eyeball, an item of confectionary or a building.

{| class="wikitable"
! Layer
! scope="col"| Explanation
|-
! scope="row"| Lithosphere/Crust (50/50 Blend)
| The {{w|lithosphere}} is any outermost rocky layer of a planet. On Earth it consists of the {{w|Earth's crust|crust}} and any parts of the upper mantle (see below) that do not convect. To say they are two distinct layers that could be blended together is rather nonsensical.
|-
! scope="row"| {{w|Upper mantle}}
| An actual layer of the earth's structure.
|-
! scope="row"| Deep mantle
| A pseudo-correct layer of the earth's structure. There is a layer called the {{w|lower mantle}}, which could be what Randall refers to.
|-
! scope="row"| Filler
| This suggests there is space in the earth that was empty, so the creator(s) added some filler to fill up the extra space.
|-
! scope="row"| Vitreous humor
|Vitreous humor ({{w|vitreous body}}) is the transparent gel inside the eye, located between the lens and the retina.
|-
! scope="row"| Mechanical/HVAC layer
| {{w|HVAC}} is an abbreviation for 'Heating, Ventilation and Air Conditioning' - the system used to heat or cool a building.  Tall buildings may have a dedicated "HVAC floor" or "{{w|mechanical floor}}" between regular floors, like an extra layer.
|-
! scope="row"| Guacamole 
| {{w|Guacamole}} is a dip or sauce made from avocados. [https://www.britannica.com/topic/guacamole Originating from  ancient Mexico], it often includes onions, tomatoes and spices. Notably, guacamole is a major component of seven layer dip, and is shown here to be the seventh layer (from the surface).
|-
! scope="row"| Cytoplasm
|{{w|Cytoplasm}} is the "flesh" of both eukaryotic and prokaryotic cells; a jelly-like substance that fills all the otherwise empty space within the cell.
|-
! scope="row"| Cork
|Due to the proximity of the cork layer and the insulation layer, this may possibly be referencing {{w|Cork (material)|cork}}-lined walls, which are used today mostly for high quality soundproofing, but have [https://www.jstor.org/stable/27135713 a considerable history]. Another potential reference could be the fact that baseballs (another spherical shape) have a layer of cork in them (though it is usually in the center). Finally, the cork is a real layer of tissue in many woody plants, part of the bark.
|-
! scope="row"| Insulation
|Probably a reference to the {{w|building insulation}} installed in the walls and ceilings of buildings.
|-
! scope="row"| Seeds
|Part of a fruit.
|-
! scope="row"| {{w|Pith}}
|Part of a tree trunk or the thick spongy layer of the skin of a citrus fruit 
|-
! scope="row"| Nougat
|{{w|Nougat}} is a family of confections made with sugar or honey, roasted nuts, whipped egg whites and, sometimes, chopped candied fruit. It often appears as layers within confectionary items (such as Snickers, Double Decker and Mars) and, notably in relation to the comic, it constitutes the second-innermost layer of {{w|Mozartkugel}}n, a spherical confection.
|-
! scope="row"| {{w|Outer core}}
| An actual layer of the earth's structure.
|-
! scope="row"| {{w|Inner core}}
| An actual layer of the earth's structure.
|-
! scope="row"| Secret core
| Likely references secret compartments that may be hidden in the hardest to find recesses of other objects or structures, for the purposes of concealing precious items or closely-guarded secrets.
|-
! scope="row"| Kinder toy capsule
| A {{w|Kinder (brand)|Kinder}} toy is a reference to a chocolate egg-shaped confection by the Kinder brand, the {{w|Kinder Surprise}}, a chocolate shell with a plastic 'yolk' capsule in the center. Though that is loose within a void, unlike this 'Earth model', it closely matches this philosophy despite (or because of) being a banned food item in the United States.
It is widely believed that this is because the 'yolk' can be a choking hazard, despite the fact that you'd have to be swallowing a chicken egg-sized confectionery in a single mouthful for that to happen accidentally, or deliberately try to consume the plastic capsule whole. The toys within, however, may contain small pieces that can pose a choking hazard, especially in the toys that are packed as components, requiring some assembly, in order to fit into the capsule. Rules about small components (in toys for young children) and the inclusion of non-food contents within food-items have been used to prohibit this product within the US. To specifically overcome the latter regulations, the {{w|Kinder Joy}} was developed; an egg-shaped packaging containing the chocolate treat in one half and the toy separately within the other.

Randall's punchline of the comic is that there may indeed be a hidden toy at the center of the Earth. The title text explains that due to the {{w|Earth's magnetic field|geomagnetic field}} not behaving as scientific models suggest it should, some geophysicists argue that the hidden toy is – or at least contains – some additional form of magnet which impacts the accepted {{w|Magnetohydrodynamics|magnetohydrodynamic}} effect. A more plausible explanation is that their model is wrong because they've based it on Randall's diagram full of spurious layers!

Since the radius of the earth is 6371 km, this gives the Kinder Toy Capsule having a radius of about 900 km (from measurements of the diagram). This gives the Kinder Toy Capsule a volume of just over 3 billion km<sup>3</sup>. Assuming a real Kinder Egg has a volume of 60 cm<sup>3</sup>, and a packing density of 63.5%, the Kinder Toy Capsule could contain 5x10<sup>22</sup> (50 sextillion) actual Kinder Eggs.
