Purugly, Huntail, and Grumpig

"If they really wanted to make it realistic, they would've made this place actually wet," the boy complained, annoyed that he'd been dragged along to the aquarium rather than taken to the amusement park.

"If it really was like the deep ocean, we wouldn't be able to breathe," his father pointed out.

The family Purugly huffed; he'd hoped that there wouldn't be an argument on this outing. But that may have been a bit much to expect out of them. Sometimes, the three kids got along. In most cases, they seemed to like nothing better than complaining and harassing their siblings. This place wasn't so bad. They were in a tunnel crafted to look like coral structures, with shifting watery light filling the whole area. Since it wasn't wet in the least, he wouldn't mind taking a nap in this place. Not now, but...

A movement and flash of light caught his eye. In a small hole near the bottom of the tunnel, there was a little gray fish with yellow eyes and fins. It was weaving side to side, but mostly staying in its spot. When the Purugly stepped closer, the fish's eyes flashed again. What was it doing trying to get his attention? Did it think it was better than him? Peeved at its insolence, he uncurled both of his tails, then wrapped them firmly around his waist so as to bulk up his front. Then the Purugly crouched and glowered at the fish. Before long, it should realize his threat and take off.

On the other side of the hole, there was a second tunnel where the ceiling displayed the largest tank overhead. A Huntail that lived in the aquarium was sitting in the hole, watching visitors pass by. Normally, he'd be in one of the tanks, keeping peace between smaller Pokemon. But he wanted something different to do today and being out of the water was an interesting experience. Like right now, there was a girl with a Grumpig entertaining a few others. "We're hanging out underwater with the Wailord! Why not dance?"

The Grumpig snorted, doing an odd stomping dance while waving her forelegs rhythmically. She had started it, with the girl soon copying. While the human was doing a good job, she wasn't nearly as fascinating as the Grumpig. The black pearls on her forehead and around her waist shimmered with power The Grumpig was smiling slyly, giving the Huntail a wink when their eyes crossed. Seeing that, he felt an impulse to start dancing along too. He made the lights along his body glow to the rhythm of the dance, swaying a little as there wasn't a lot of movement he could make in the tunnel.

At the other end, the Purugly growled as the little fish began bobbing more energetically. Why was it mocking him? It was just a little bitty fish out of water and he regularly snatched fish bigger than it out of the pond near home. He should take a bite out of its fins to teach it a lesson. After watching it a few moments longer, the Purugly pounced and chomped down on the fish.

Immediately, both the Purugly and the Huntail screamed in pain. The latter's fins were tough, making the former's mouth bleed. The false fish on the Huntail's tail had a few tiny dents, but the suddenness had startled him more than any pain. Furious but a little bewildered by the Grumpig's dance, the Huntail darted out of the hole and lashed out at the first one he saw, the dancing girl. His tail knocked her over, but then the Grumpig intensified her dance and pointed to him. Psychic power blasted the Huntail, knocking him through the tunnel wall and into the Purugly. The Purugly squalled, swatting the Huntail before running off with his violet fur all fluffed up.

The people there stared at the scene for a moment, stunned at what had happened. The Grumpig swayed and smiled as if innocent. After all, she couldn't have had anything to do with that. She couldn't have known who was in the other tunnel or what would happen if she made the Huntail dance. There was nothing wrong with dancing.

She was totally... not innocent. But they didn't need to know that.

…

Purugly Platinum entry: It binds its body with its tails to make itself look bigger. If it locks eyes, it will glare ceaselessly.

Grumpig Emerald entry: It stores power in the black pearls on its forehead. When it uses psychic powers, it performs an odd dance step. Its style of dancing became hugely popular overseas.

Huntail Emerald entry: To withstand the crushing pressure of water deep under the sea, its spine grew very thick and sturdy. Its tail, which is shaped like a small fish, has eyes that light up.

haha, well sometimes you don't need lots of words.
