Mold and Leeches Triumphant!

The contest was vicious, but the winners have been decided!


In a startling upset, Poisonous Subterranean Mold surged to the lead. Ravenous Troglobitic Leeches held strong for a second place showing. Early favorite Blind Albino Crabs were edged out of the running.

So, the two monster encounters going in the book, brining the total to 12, are Poisonous Subterranean Mold and Ravenous Troglobitic Leeches!

Fear not, though! The remaining four beasties are lining up for another match. All we have to do is reach $12,500!

Let your friends and enemies know!

The Madness of Metronax?

Giant mutant frogs meet giant magical ants


Jordy Williams, the genius behind Wizards with Laser Rifles, creator of the Silam zines, and I are teaming up to highlight each other's adventures. His, The Madness of Metronax, is an adventure filled with magical giant ants controlled by a maniacal ant wizard. It's going to be unreal! We thought that giant magical ants and giant mutant toads were a good fit, so if you back both of our campaigns, you'll get a cool sheet of stickers featuring artwork from both of our adventures. Looking at what we have so far, art-wise, these stickers will be insane!

Back The Madness of Metronax!


What is a Bobugbubilz?!
about 2 months ago – Tue, Apr 14, 2026 at 05:13:26 AM


Wart-ridden demon patron of all slimy wriggling putrid things


Bobugbubilz [bo-BUG-bub-ilz], the Toadfiend God, is the slimy god of evil amphibians, turbid water, and slime. A chaotic power of mires and malodorous life, Bobugbubilz is content simply to spread his putrid offspring across the planes and let them multiply and sow discord and misery where they will. Cults spring up now and again in his wake, carrying out deviant rites and spawning new creatures in his name.

Bobugbubilz has been described as a whip-wielding, bloated, toad-like monstrosity of alarming size, with a rancid odor that precedes him. But, I prefer my deities a little more unknowable. I see Bobugbubilz more as an unblinking, eternal amphibian eye in a sea of rancid frogspawn, at the center of a perpetually exploding wave of tadpoles, pollywogs, toads, and frogs.

If the campaign reaches the absurd amount of $18,500, all backers will get a print or PDF poster depicting the Eye of Bobugbubilz! I made a smaller version as bookmarks (which everyone will get a copy of).

5E Backers: 5E (2014) or 5.5E (2024)

That is the question.


For those folks who backed the 5E version of Mutant Spawn of the Toadmother, here's the big question: Do you want 5E (2014) or 5.5E (2024)?

The main differences from a design perspective are in the monster stat blocks and the character backgrounds. There will be some mechanical differences, but they won't be huge.

Because of the unique starting point of the adventure, players will be encouraged to choose a background from those provided in Mutant Spawn of the Toadmother. You may have been a noble, a sage, or a soldier, but now you are a refugee, a derelict, or a goon. Hardship has knocked you on your back and maybe given you some interesting new skills.

Backgrounds differ mechanically between 5E and 5.5E, so we need to know which path to take.

In 5E, backgrounds affect your skill proficiencies, additional languages, equipment, and suggested characteristics, and grant a unique feature.

In 5.5E, your ability scores, origin feat, skill proficiencies, tool proficiencies, and equipment are affected by your background. 

It's your call. I have my opinions, but this is your adventure, and you should decide. Keep in mind that 5E content is supposed to be compatible with 5.5E, but 5.5E is not very compatible with 5E. As a result, I'm putting my thumb on the scales—a two-thirds majority will be required for 5.5E to win.

Let me know in the comments how you feel about this. I promise to ignore everyone equally.

I am incredibly grateful to all of you who have elected to support Mutant Spawn of the Toadmother. We have been grinding through the stretch goals! So far, we have two new monsters (be sure to get your vote in below), a sticker sheet (for print and PDF pledges), and VTT tokens of all of the NPC and monster art, suitable for your favorite virtual tabletop.

On deck, we have another sticker sheet, two more monsters, and my favorite: a "Bobugbubilz is my Copilot" bumper sticker. As we cross these new thresholds, more will be revealed! Let your friends and enemies know!
