Up next is The Dragon Bestiary, which is, I think, really starting to get to its fully polished “final” form of numerous monsters that are tied into the theme of the issue. In this case, it’s the high seas and sea creatures. The first creature I’m converting is the hilariously-named giant carnivorous clam. Since this is a beast, I’m going to dispense with most of typical monster block entries.
For the record, actual giant clams can be nearly four feet across and weigh more than 440 pounds. Here’s a video of one opening up. The monster clams are bigger and much faster. I like to imagine it Pac Man'ning it's way towards the party.
I did some research, and it turns out that maybe one in ten thousand clams produce pearls (and only a fraction of those produce jewel-quality pearls; the numbers seem to be the same for oysters as well), but that’s modern-day real world numbers, where over-fishing and pollution and whatnot have probably skewed those numbers down. Giant clams, however, are a bit more prolific when it comes to pearling themselves.

Giant carnivorous clams resemble their smaller kin and seem to come in as many different varieties. Many are solitary, while others live in small clusters of up to a dozen. They are as edible as regular clams. Although primarily filter feeders, they will gladly eat larger animals as well. They clamp down on any creature that swims close, wait until its stopped struggling, and then draw the potential meal into its body.
Giant Clams, Giant Pearls. A small number of giant clams (about one in a hundred) produce pearls. They usually have a lustrous brown or reddish sheen to them. These pearls are worth quite a lot, although they aren’t as high a quality as the pearls produced by regular clams. More often, they produce nacre—mother of pearl—which is less valuable but still in high demand for use in ornaments and jewelry. About one in twenty giant clams produces usable nacre.

Actions
Ram. Melee Weapon Attack: +6 to hit, reach 5 ft., one target that is behind it. Hit: 9 (2d4+4) bludgeoning damage.
Clamp Down. Melee Weapon Attack: +6 to hit, reach 5 ft., one target. Hit. 9 (2d4+4) bludgeoning damage and the creature must make a DC 14 Dexterity saving throw or have one limb, determined randomly by the Narrator, caught in the clam’s shell. The creature is grappled (escape DC 14) and is restrained.
Siphon Toxin (Recharge 5-6). The clam releases a poison into the water around it in a 5-foot radius sphere. The area becomes lightly obscured and each creature in that area must make a DC 11 Constitution saving throw or be incapacitated for 1 minute. A creature may make a new saving throw at the end of each of its turns, ending the effect on itself on a success.
Bonus Actions
Clammed Up. The clam shuts its shell. Until it opens up again, its AC is 17, its speed is 0 and can’t increase, it has disadvantage on Dexterity saving throws, can’t take reactions, and the only action it can take is a bonus action to emerge.
If the clam is currently grappling a creature that is Medium or smaller and it has not swallowed anyone else, that creature is swallowed by the clam. A swallowed creature is blinded and restrained, has total cover from attacks outside the clam, and takes 5 (1d10) acid damage at the start of each of its turns.
Combat
The giant carnivorous clam starts by releasing toxins, then rams creatures that are still trying to attack it. It usually says its Clamp Down attack for creatures that attempt to touch it while it is filter feeding.
