I might be gone for the next few days, so I'll have to do this now. Thank you, Asylum, for that comment.
Mollux, the Lamp Shell Pokémon
Black: The bioluminescent lamp on its back is remarkably light, allowing this Pokémon to move quickly in and out of water. White: Mollux shells have different patterns depending on their habitat; rare varieties are highly prized among collectors.
Kaprikorn: The Black entry is fine, though it leans on the scientific side. Not that that's bad, of course, but it's just noticeable As for the White entry: I don't see how it connects to snails other than that they're slimy to start with. How would a glue work?
Jirachi6: I'm unsure of using 'fire pokemon' in the White entry, as it sounds technical and non-natural, though I'm not sure how to replace that. Otherwise, the entries are good.
fryfrey: A comma after 'maneuver' in the Black entry would be proper. The overall in that entry could also be trimmed, as mentioned before.
Drifblim: The Slugma thing amuses me, and I don't really care how logical or illogical it is, seeing it's quirky and fitting. But yay entries! :D
capefeather: I do like that dichotomy between the liquids in Mollux's shell. :) The Black entry is realistic, but of course, that's not bad. It gives an alternative choice to some of the more odd options available. (I changed my entry about swallowing food whole, lol.) Rocket carrot Mollux makes a return, though the entry for that is a tad long for my tastes. The actual content is fine, though.
Bull of Heaven: Black's entry reminds me of capefeather's. I have to admit, capefeather's is more strongly worded. The White entry, on the other hand, provides a very feasible explanation for Dry Skin while not being too obvious. I like that one very much!
Project_Mars: "Despite this" should have a comma. Otherwise, good.
CiteAndPrune: "When heated into a gas" and "Combined with water" should have commas after them. Otherwise, good.
Eszett: Oh, that part of Mollux. Well, it'll be good for implications and those who enjoy those sort of pokedex entries. The White entry seems a bit contrived to explain their lighting, though the 'light show' sounds fascinating.
Eagle4: You can lowercase the Shuckle name now. :) 'Territorially' has two Ls. I'm not sure on Shuckle and Mollux playing together and then suddenly fighting each other on territory. White's entry is curious and otherwise fine, though Black's is still a bit weak.
GRs Cousin: I don't think extra entries are allowed, but otherwise, the Black/White entries are fine and good. I do think slightly more variety could be better, but hey, it's fine to me! Mood lamp snail. :D
kickmeimirish: Generically good.
Darklatias92: Well, sorry for changing my White entry, but the comment I got on my White entry coerced me to change it. Is it still fine with you? Respond quickly if you want me to react. XD
CiteAndPrune: The Black entry is... well, I don't really like it. It combusts from the presence of oxygen? That might clarify the wording. The latter sentence just has a bit of a roundabout wording to it.
heatran1919: Sounds adequate to me! White's entry is especially adequate.
Skore: No, I don't like the role reversal in the entries. Maaaaybe if it was for Ruby/Sapphire (ahaha...), but it's just repetitive. 'Its' has no comma for a possessive. I do like the internal oven/cooking thing--I wish I had thought of that. I'm okay with the scalding brine part, though I'm just as confused by it. Erupt from its mouth, lamp, or ground?
SubwayJ: Black's is suitable, while White's is still unsatisfactory to me. I do think you should change the mystery of Mollux's lamp's insides... though, hey, Shedinja does something similar and gets away with it.
Mh… I'm fine with the new entry, to be honest. I think I suggested something like that in another post…
Well, I can see this Pokémon with different colors and patterns, like real lava lamps. Sounds fitting! :)
Black: It attracts prey with its glowing shell. It stings its victims with a powerful poison, then swallows them whole.
White: It burns the two liquids in its shell to attack enemies with a scorching flame, even underwater. These liquids are sometimes extracted and used as rocket fuel.
I can't really find a good way to shorten my White entry, but it's not *that* long so it should be fine. Black is, I suppose, more of a "generic anchor" while White kind of goes further with how the shell functions.
Thanks for all the comments. Since the 24 hour warning is in effect this'll be my final entry, as I'll be gone until tomorrow. I combined the Fire and Poison hints into the White entry so I could make more room for Dry Skin in Black... I've revised that several times until I settled for this, and it'll have to do. >.>
Mollux, the Mantle Pokemon
Black: On sunny days its liquid toxin evaporates over time. Mollux must find water to refuel before the shell empties or suffer dehydration.
White: Its toxin is cooler than the lava bubbles. By adding water Mollux turn it into acid, while oxygen and heat produce an explosive gas.
Black: In some cultures, drinking the fluid from its shell is said to be the mark of a true man. In others, it is said to be the mark of a true imbecile. White: Its harpoon-like tooth is renowned for its effectiveness. Some island communities like to use them to slice their fried Magikarp.
NB. Species name is a pun on "Astro Lamp" and "Gastropod" in case anyone was wondering.
I don't have a hope in hell of being slated but I hope we have all learned something from this. This was certainly one of the better Dex entry threads in recent memory, if only because there was an actual argument. To be quite honest none of the submissions stand out to me, but that's probably a good thing as it means none of them are too outlandish or objectionable (though I do think that Dex entries ought to be one of those things we can have more fun with, it appears some others take them very seriously indeed...)
Mollux, the Lava Lamp Pokemon B: It is still unknown exactly what is inside its lamp, but it produces a bright glow that attracts wild Pokemon. W: Despite its weight, the sticky substance it excretes from its tentacles allows it to stick to walls.
