Single-Celled Organisms

This comic features a lot of single-celled organisms.

Amoebas
A number of strips focus on a group of amoebas who live in a petri dish somewhere in the lab. They can speak and look like green blobs with arms and faces. One of them is named Frank, which is actually the same name as one of the bees.

Bacteria
In the Wizard of Oz parody, Thaddeus Euphemism is shrunk down to microbial size and meets several bacteria. These include a purple bacterium with many eyes and tentacles who loves "poonooboo berries" despite them being bad for him, an orange bacterium who wants to be smarter, and a red, fuzzy bacterium who wants to be scary. The many-eyed bacterium later features again when another scientist is shrunk. He also meets harmful, red bacteria called "Widdles", and two bacteria-eating microbes.

In one strip, Thaddeus observes some bacteria spelling out "GET LOST" and thinking, "How rude!".

In another strip, some bacteria spell out "Plz make it stop" and then ask for a raise.

In the Bacteria city arc, some bacteria build cities and then go to war with one another.

During the final strip of the Covid-19 arc, Thaddeus freaks out when his microbe-detecting glasses detect bacteria, even though covid-19 is a virus and most bacteria aren't pathogens.

In one strip, Thaddeus and a bacterium flirted with each other.

Viruses
One strip shows a "retrovirus" as a virus in retro clothes.

Another shows a virus disguising itself as one of Thaddeus's cells, thereby infecting him with flu.

One story arc focuses on Thaddeus inventing a virus that makes computers throw up.

One strip involves two immune cells beating a virus, only to have a tougher, mutated version show up.

Thaddeus's cells
In addition to the aforementioned flu strip, one strip shows Thaddeus's cells being too lazy to multiply.
