Commander of the Worm Guard
Captain Wiggleworth
Bravest wiggler in all of VermiTopia. The Captain leads the Worm Guard, a squad of millions of earthworms who live in the kingdom’s filter beds and gobble up organic gunk around the clock.
A kingdom beneath your feet
Where Earthworms Rule the Land... and Clean the Water!
Meet the Worm Guard
Tiny heroes. Giant wiggles.
Deep beneath the ground, the earthworms of VermiTopia work day and night to keep the kingdom’s rivers sparkling. Say hello to the bravest squirmers around!
Oxygen Officer
Bubbles
Bubbles is obsessed with oxygen. She knows that when oxygen runs low in a river, fish and other critters struggle — so she’s BODzilla’s number-one rival.
Junior Soil Ranger
Sprout
The youngest hero in VermiTopia, Sprout asks a hundred questions a day and is always found in the Royal Gardens, proving that healthy soil means a healthy planet.
Tiny Allies, Giant Impact
The Microbe Squad
Too small to see without a microscope, the Microbe Squad lives on every grain of soil and every worm casting. Worms and microbes are best friends — they clean water as a team.
Uh-oh... trouble in the water
The Pollution Villains
They’re messy, they’re rowdy, and they’re hilariously bad at hiding. Each villain represents a real kind of water pollution that scientists measure and treat.
VillainRepresents: Biochemical Oxygen Demand (BOD)
BODzilla
“Slurrrp! More oxygen for MEEE!”
A big, goofy, always-hungry monster made of organic waste. As bacteria break him down they gobble up oxygen in the water, leaving fish gasping. He slurps oxygen like a milkshake.
VillainRepresents: Total Suspended Solids (TSS)
The TSS Tyrant
“Behold my kingdom of MUD!”
Self-crowned king of murk. The Tyrant clouds water with tiny floating particles that block sunlight, smother fish habitat, and carry other pollutants along for the ride.
VillainRepresents: Mixed chemical contaminants
The Chemical Chaos Crew
“You can’t catch us ALL, wormies!”
A rowdy gang of contaminants — excess nutrients, oils, and other troublemakers. Some can be reduced by biological treatment, but others are tough customers that need different tools entirely.

The brilliant minds behind the wiggles
Every kingdom needs wise advisors. Meet the real-world inspired team: George in worm science, Geri in research, and Jerad in field operations.
The Worm Doctor
Dr. George Damoff
The Royal Wormatorium
Chief worm scientist of VermiTopia and trusted mentor to every hero in the kingdom. When pollution strikes, the Worm Doctor studies the problem, rallies the worms, and finds a natural solution.
Give a worm a chance, and it will change the world — one wiggle at a time.
Inspired by a real Perca scientist
R&D Manager
Geri
VermiTopia Research Laboratory
Geri runs the VermiTopia Research Laboratory, where she designs experiments, tests new ideas, and helps players invent pollution-fighting technology for the kingdom.
Every experiment teaches us something — even the messy ones!

The Worm Wrangler
Jerad
VermiTopia Field Operations
The hands-on field leader who keeps worm beds, pumps, pipes, and treatment systems running. When the kingdom needs a practical fix, Jerad brings the tools and gets to work.
Healthy systems. Happier worms. Cleaner water.

Earthworm Biology
Earthworms have no lungs, no eyes, and no bones — and they’re still among nature’s most important engineers.

Vermifiltration
Vermifiltration trickles wastewater through layers of wood chips, soil, and gravel packed with earthworms and microbes.

BOD & TSS
Two of the most common ways to measure water pollution are BOD and TSS — the real-life versions of our villains.
Dig deeper - Why clean water matters
Water Pollution
Pollution can come from homes, farms, factories, and streets. Treating wastewater protects rivers, lakes, and drinking water.

Some of our heroes are inspired by real people
VermiTopia is an independent, imaginary world — but Dr. George Damoff and Geri are affectionate cartoon tributes to real scientists at Perca, a wastewater treatment company in Walla Walla, Washington. Perca uses earthworms and biological treatment systems to help clean real wastewater.
