Forge Monsters

At the behest of noisms. Stats are provided in the form of references to similar Pathfinder monsters, along with any modifications necessary. If you need combat statistics for a bubble worm I'm not sure I can help you.

Crimson Seeker Asp

The crimson seeker asp is a sort of clockwork device, studded with diamonds. When dipped in wine, their color darkens to a deep, blood red, and the asp will unerringly seek out the nearest person from the region of the wine's origin and attempt to bite them. (What constitutes a wine "region" is left to the particulars of the campaign world. It might be as large as, say, France, but could be as small as a particular county or vineyard.) If the region produces on white wine for some reason, you are out of luck: the asp despises white wine, and will be rendered permanently inert if immersed in it for any extended length of time.

In combat, treat as a venomous snake, except that its poison deals 1d4 Wis damage. (For an asp treated with a wine of about 10% ABV. Weaker varieties might deal as little as 1d2 or even 1 points of Wis damage, while stronger varieties might deal as much as 1d8.) After 3 bites, or once it is reduced to 0 hp, the color drains out of the crystals along its back and it becomes inert again.

Bubble Worm

Appears to be a chain of tiny iridescent bubbles. It's actually a sort of creature. It eats secrets (or, failing that, silk). Every secret uttered in its presence is forgotten by one creature who knows it, and the worm adds a bubble to its length. A properly prepared sorcerer can read the secrets from the bubbles, though this destroys the bubble in question. The worm will resist such treatment, as it causes them great discomfort and can even kill them if carried on long enough. (10% chance per bubble read, +5% cumulative for each bubble in a single day.) If it absorbs an entire secret, to the point where no one living remembers it anymore, it lays an egg. The egg is worth 100 gp x the number of creatures who once knew it. It is commonly worn by the nobility as jewelry in certain decadent courts.

Vapor Cat

It appears to be an entirely ordinary cat, usually grayish, though sometimes cream colored or even blue. Wherever it goes, fog goes with it. When half a dozen or more gather in a single place, it rains. If a vapor cat gets wet, it dissolves. The puddle-cat maintains its general organization and can slip around at will in this form; with a little work, it can be coaxed into a warm bottle. Poured out in a warm, dry place, it will reform into a cat (though slightly different in appearance, to the discerning eye) and regard the owner of the bottle as its master. They make pleasant (if slightly damp) companions, but are useful only insofar as they are unchallenged at catching magical vermin, which they carry to their master mostly undamaged.

Fur Lobster

Not actually a lobster. It's a large, crustacean-like monster that makes nests for its eggs that it lines with fur. To that end, it is weirdly attracted to fur and hair. The small ones simply seek it out where it's already fallen, or remove it from sleeping creatures. The larger ones can be extremely aggressive, and seek out warm-blooded mammals to attack and eat, the larger and furrier the better. Treat as a giant scorpion, but without the sting, and an uncanny ability to track warm, moving objects over long distances.
