Entranced, Tyler continued scrubbing the pool, working the brush up and down the algae-scummed sides until the algae swirled off into the filthy water. His muscles as he did so became larger and more defined while his legs became longer and he grew taller and taller. He admired how he looked in the glass of the sliding glass door that led back into the witch house. It was almost unreal, but he also realized that if he wanted to get the pool really clean, he'd have to drain it. And that meant going down into the scunge-choked hole of the deep end.
But the old woman seemed good to her word so there was no help for it. He waded into the deep scunge, feeling around with his toes then suddenly slipping on the slime and choking on a mouthful of algae-choked water. He swallowed some of it, then struggled to the surface, gasping for air and covered with long threads of algae. But he felt stronger and Tyler was man enough for any challenge. The old woman had set him a task of cleaning her pool. Well, he'd get it clean all right.
He dove down into the dark water, feeling around on the bottom for the drain. His lungs burned and he had to let go, but he swam up and caught another breath then dove down again, knowing where it was. At last he was able to wrest the cover free, then he was able to turn the switch to open the drain. The suction nearly caught him but he felt stronger yet, bracing his feet against the bottom of the pool and pushing off until his head broke water.
Strangely, Tyler noted, his feet were still on the bottom of the pool but his head was out of the water. He hadn't expected it to drain that fast, but then he realized that as the water in the pool drained down, he was growing taller. He grabbed the pool brush and scrubbed at the sides, able to sweep the whole pool down with a few strokes from his massive arms until the last of it burbled down into the hole between his feet as he stood there in what for all the world looked like an empty, if clean, child's wading pool.
A tiny little old woman came out of the house. "My!" she exclaimed. "Such enthusiastic cleaning! I hadn't expected you to actually DRAIN the pool, but a bargain's a bargain and you look like a fine strong young giant who should have no trouble at this 'beach' you used to dread."
Tyler looked at himself. He had massive bodybuilder muscles, but that paled next to the fact that he was standing in the bottom of what had to be a nine foot pool and he was looking out the top. And what's more, the Speedos she'd give him were stretched nearly to bursting.
The tiny old woman smiled. "Off to the beach with you then!" She took out a sparkling emerald wand and waved it and next thing Tyler knew, he was standing on the beach.
