'Damn it, this is going too slow." He was irritated at his small arms and legs. They were too small to swim with. He reached out with one arm, kicked with a foot, reached out with another arm while retracting the other, kicked with the other foot. No use, he never really moved, although it was partly the streams fault, as he swum against it. 'And why's my tail split? I know it's normal for Buizel to have a split tail, but what do they do with it?' He thought angrily. There, on the opposite side of the river, which had become much bigger since he had started swimming, he saw another Buizel. It was not there before, strangrly enough. It also looked like it could outswim Waterfall anytime. "H-hey!" Waterfall shouted to get it's attention.
"Huh? Oh, hi. Didn't see ya there, Slowpoke." The Buizel slowed down to a pace similar to Waterfall.
"Wha..? Slowpoke, I'm a Buizel, idiot. Get glasses!" He didn't really know what glasses were, but somehow, he knew still. Weird.
"What's glasses? Anyways, why are you swimming like that, weirdo?" It only smirked, it was obviously a boy, when you listened to his voice, although it was kind of difficult, considered water covered your ears in this case.
"You're the weird one, you don't even know what glasses are!" Waterfall was getting slightly pissed off by this guy. "And what do you mean 'swimming like that', I'm swimming normally, like any other human would!" 'What? Did I just say human? I'm getting mad from this memory loss!' "I-I mean Pokémon!"
"But your tails aren't moving at all!" The Buizel pointed at his tails, which hung limp after him, following the water's surface.
"Wha...?" Waterfall glanced at the Buizel Boy's tails. Unlike his, they were moving in a circle, propelling the Buizel forward, it looked like they could go much, much faster than that, even! "Oh... I get it..." Then he tried the same. He ordered his tails to move, and they did. He told them to move in a swirly, circle pattern, and they did, and he propelled forward, past that Buizel and all.
Just there the river split, and the two Buizel separated, not like Waterfall cared.
After some experimenting, Waterfall gained full control of his tails, and he could swim slow and quick, swim under water and jump into the air, he could move in every direction and everything! It was a delight to be able to swim at full pace.
About a minute later, he had to rest a little bit on land. Then, he heard a faint noice in the bushes, like a twig breaking in half under the weight of something.
"Who's there?" Waterfall shouted and looked towards where he heard the noice. He stared at the bush, waiting for the something to come out, if anything.
