Dem's story 

Now this is a good one! Several years ago, a shipload of mermaids were passing through on their way from Acqua to Oceania. They were all in their human-like two-legged forms, it made getting around the ship so much easier, but they took one look at the Pub inside its glass sphere and saw the possibilities. 

They drew up outside the airlock and trooped inside, all twenty of them, long legged and rather gorgeous looking with big smiles on their faces. The regulars, Angus included were staring so fixedly at the first mermaids coming through the door that they didn't notice when the last two discreetly dropped a small bag of blue crystals down into the bottom of the sphere. 

The mermaids sat down and chose fancy drinks with little umbrellas in them, all except a couple of older ones who went straight for the Limeburners' whisky sitting on Dem's table. Chatting happily amongst themselves, they managed to be the focus of everyone else's attention, which was why no-one realised the sphere was filling up with water, until Angus noticed a funny sloshing sound as he strode around behind the bar. 

"What the-!" swore Angus in astonishment staring at his wet feet. 

A tall mermaid with thick long blond hair stepped up to the bar and leant on it with a seductive elbow. "What's the matter possum?" 

"The floor ... there's water all over it!" stuttered Angus, still not quite believing what he was seeing.  

"Yes, isn't it wonderful?" She batted long lashes at him. 

"Is it?" asked Angus doubtfully, still bemused by the vision in front of him. 

The water was now up to his knees. He looked down, hoping there was nothing behind the bar that would be ruined. "Don't worry, it'll stop in a few minutes," said the mermaid kindly. "When it gets to about here," she held a hand out about a metre above the floor. 

Sure enough, the water stopped rising as she had said, leaving everyone rather bewildered to find themselves sitting waist deep in cool water. All of a sudden, there seemed to be a lot of splashing going on. As one, the mermaids quaffed their drinks, tossed a shower of blouses onto the table top and disappeared below the surface, brightly coloured tails flicking water everywhere. In a flash, the door was pushed open and most of them swam out, followed less gracefully by most of the regulars, eager to get a glimpse of naked breasts. 

Angus was trying hard to get a grip on his sense of reality.  

"Hey!" his voice came out as more of a squeak than a yell. He cleared his throat and tried again. "Hey! We can't have this! This here's a pub, not a swimming pool! You'll have to get rid of the water ..." his voiced trailed off as all the regulars and most of the drop-ins, turned as one being to glare at him. "As soon as it's convenient," he muttered. 

He picked up a cloth and wiped futilely at the drops of water on the bar. 

"I don't suppose you've got any fish?" asked one of the mermaids, popping up in front of Angus. "Any sort will do." She smiled. Her small white teeth looked unusually sharp.

Angus drew back apologetically. "Sorry! Only frozen fillets. For the fish and chips, you know," he explained quickly, trying not to look at the pointy teeth or at the pair of breasts, both of which suddenly seemed rather threatening.  

"I could cook some up for you," he offered hastily. "No trouble." 

The mermaid looked a little disappointed, then accepted gracefully. "Thank you that would be very kind, but don't worry about the chips." 

The mermaids stayed for another ten hours, having a wonderful time swimming around outside the pub and providing excellent entertainment for passing ships, some of which came a little too close for comfort. Angus couldn't help wishing he had some way of selling tickets. By the end of the ten hours, the rest of the customers were feeling rather soggy and were quite glad to see them go, despite taking their breasts with them.  

Luckily, they syphoned off most of the water first, although it took Angus ages to mop up the rest. Dem can still show you the water mark on the side of the Pub, if you offer her a drink.
