crack of a mouth.
âHello,â said Ruby. The rock didnât reply.
She picked the rock up. It was as heavy as the baby next door.
She put the rock up close to her ear, but it was silent. She whispered to it, but it didnât reply.
She breathed in its cold cellar smell. Nothing like the kitten . . . but it did smile. Ruby smiled back.
âIâve got a pet! IâVE GOT A PET! â She rushed into the kitchen. âLOOK!â
Ruby put the rock on the table. Jane and their parents came to look at Rubyâs pet.
Jane laughed. âThatâs a stone.â
Mum stroked it. âItâs a very nice one,â she said.
Dad turned it around in his hands and examined it carefully as if it were very precious. âItâs a very fine specimen.â
âIs it?â asked Ruby. âOh, Iâve got a pet specimen. It must have fallen out of the sky.â
Dad grinned. âFrom Planet Droppablock, perhaps?â
âYes,â said Ruby. âI think Iâll call it Rocky. Rocky from Planet Droppablock. My pet.â
âThatâs just so silly,â said Jane. âIt canât be from another planet. Anyway, thereâs no such thing as a pet rock. A pet has got to be alive. Itâs got to breathe!â
Ruby didnât say anything. She stared at her smiling rock. That was a tough one. It had to breathe. Huh.
âTrees breathe,â said Mum, âyou just canât see them doing it.â
âAha! See!â cried Ruby. âIt
is
alive!â
Chapter Three
JANE TOOK KITTY to her room. She found a cardboard box and cut a doorway in it so Kitty could squeeze in and out. She put in an old jumper and an old cuddly monkey. Kitty went straight insideand rolled on her back and tussled with the monkey. When the monkey was dead she ran in and out chasing her tail.
Ruby watched, thinking, Huh! She found a shoe box still lined with tissue paper and put in a scrap of blanket. âThis will make a lovely bed,â she told her rock. She had lots of cuddly toys on her bed, but none she could spare.
âI hope you wonât be lonely, Rocky,â she said as she took the box down to the playroom.
Then she remembered the pebbles in her pocket. âTheseâll keep you company.â She slipped the pebbles into the box â three smooth and two knobbly â and laid the rock on top.
âThere,â she whispered. âThatâs cosy, isnât it?â
Jane came in. Kitty was snuggled under her chin, purring. âWhat are you doing?â she asked.
âMaking a bed for my pet.â
âSilly, you know itâs not a real pet. Look, if it was alive and a real pet,â said Jane, âit would move, like Kitty.â
Ruby stroked her rock. It was cold and hard and it didnât move. âThings are different on Planet Droppablock. It moves so, so, so slowly, you canât see it,â she said. âLike a very, very, very slow snail.â
Janeâs mouth fell open. She didnât know what to say.
Ruby liked it when Jane was lost for words. She smiled. And the rock went on smiling too.
Jane sat down and Kitty leaped around the room, bouncing over the chairs and fluffing up her tail like a brush.
âShame your pet is so slow,â Jane said, throwing a sponge ball for Kitty. âI mean, you canât have much fun with such a slow pet, can you?â
âHuh,â said Ruby.
Kitty jumped and cartwheeled around the room after the ball, leaping on invisible mice and chewing her cuddly monkey.
Then Ruby noticed something: the kitten had made a puddle on the floor.
âMum! Mum!â she called.
âWhat is it?â
Ruby pointed. âThat naughty Kittyâs made a puddle,â she said quietly.
âOh dear, never mind,â said Mum. âThatâs what kittens do. Jane must clear it up.â
Jane made a face. âYuck! Itâs smelly. I donât want
