Harry the Poisonous Centipede. Lynne Reid Banks

(This was because the Up-Pipe was a drain, which carried away a Hoo-Min’s dirty shower-water. But Harry didn’t know that.)

      He was determined not to be put off. He turned round and tried the water with his back feelers.

      That was all right. So he walked backwards until his rear five segments were in the pool. Six. Seven. Eight. Nine. Now he was nearly halfway in, and his tail-parts began to float to the top.

      He couldn’t hold them down. Was he swimming? He wriggled his rear nine pairs of legs and his body moved about. That was swimming, surely? He backed a little further. And a little further…

      Whoops!

      With only a third of his body-length still on shore, he began to lose his grip on the earth with his front legs.

      He clawed frantically with his first seven pairs of legs, digging the tiny claws on their tips into the soft, wet earth. But there was too much of him already floating in the scummy water. Something seemed to be pulling at him, dragging him away from the safe ground.

      But Belinda was far away and couldn’t catch his signals.

      Harry clutched and tugged, and sent out signals of distress, but nobody came, and the water kept pulling until first one, then another, and finally all seven front segments left the shore. Harry found himself struggling in the deep, dark badsmelling water!

      Kicking and squirming, he was carried along through the darkness. He kept going under, and the water entered his breathing holes (he had one in each segment). He would blow it out and pop to the surface again but he knew he couldn’t go on doing this for long. He was choking – choking all along his length. It was terrible! He was going to drown!

      He sank beneath the surface once again. “I’m dead!” was his last conscious thought. “Oh, Mama!”

       5. Harry Upside Down

      He woke slowly. He felt awful. Truly awful.

      The world was all wrong, somehow.

      Harry’s eyes weren’t good anyway and now they were useless. They seemed to be staring straight into the earth. Something hard was pressing on the back of his head. His legs weren’t touching anything. He kicked them about, trying to run, but it was no use. He thrust out his poison-claws, which was always his reaction to danger. They closed on emptiness.

      He slowly realised how he was. He was upside down, a position he’d never been in before. That was why he felt so funny.

      He didn’t realise how lucky he’d been. He’d been washed to the side of the pool, or stream, or whatever it was, on to his back. Because of this, all the water that had got into his breathing holes had drained out. Of course he still couldn’t breathe very well because some of the holes were now blocked by the ground.

      He struggled to right himself, rocking this way and that, wriggling and twisting.

      With a final jerk, he managed to get his front half round the right way. After that, it wasn’t hard to turn the rest of himself.

      He looked around. The pool wasn’t there any more. Just a long muddy channel. It seemed that the water flowed down it, like the rainwater in Harry’s regular tunnels, and then soaked away, somehow.

      Harry tested his twenty-one segments by lifting them one by one off the ground, and all his forty-two feet by moving them in the air, in a sort of ripple, first along one side of him, then along the other. They seemed to work. What a relief!

      He tried to run. He found he could! He did. He ran as fast as he could run in the direction of home. (He knew by instinct which direction to run in.)

      As he ran, he tried to think. Should he tell his mother what had happened to him?

      Probably better not. Even though he hadn’t done the one thing she’d told him never to do – go Up the Up-Pipe into the Place of the Hoo-Mins.
