I don't think so, but let's give them an "as characters" paragraph. Favored class wizard?
Sure, put in a Flawder As Characters section, we've already got Wizards as favoured class.
As for the text. Firstly, if they are MARINE creatures they wouldn't live in lakes, so I'd cut that out. The bit about their shells not being spiralled ought to be in the
description. Some of the rest of it can be paraphrased. Oh, and I reckon a weight of 60 pounds for them:
This creature resembles an upright snail, although its beautiful shell does not spiral like a snail. Two eyestalks sprout from its head. A pair of tentacles extend beneath the eyestalks, above a round mouth with several rows of blunt teeth.
Flawder are peaceful nomads who roam the floor of seas and large lakes. They live in small tribes, each tribe has shells of a different, distinctive pattern and coloration.
Flawder are hermaphroditic and can breed at any time, producing 2-12 soft eggs per pair, which they hide throughout their territory. Flawder reproduce at an alarming rate, hatching in 6 weeks and reaching adulthood in 6 months. If predators are absent, a tribe of flawder will quickly grow so numerous it eats all plant matter in the area, resulting in the tribe's death by starvation.
Flawder are led by wizards. A flawder chief rules absolutely, leading the others in search of food. In rare instances, a chief leads their tribe to attack a particularly dangerous predator.
All of a tribes' leaders share one "spell book" make from inscribed flat pieces of shell. This spell book is carried by a specially chosen common flawder. Tribes may also carry 1-20 similar shell books which record histories, legends, and songs. A few flawder carry special or magical items, mostly crafted by their wizard leaders. A flawder may contain gemstones or pearls in its gullet, and their beautiful shells are valued as artistic works.
Flawder are quite tasty, and are therefore hunted by many other races. As a result, flawder are nervous around almost any other aquatic race, but will sometimes associate with tritons, mermen, or aquatic elves.
A typical flawder is 3-1/2 to 4 feet long and weighs about 60 pounds. A flawder can live for up to 40 years.
Flawder speak a dialect of Aquan in a beautiful, musical tongue.
