It was dark, but warm and somehow friendly and welcoming. Then suddenly there was a “Crack-Zooooosh!” as millions of packets of computer information – electronic data, as it’s called - shot by at the speed of light, on the way to a computer somewhere in the world.

It reminded Dot of being on a train when you saw another train coming towards you on the next track. It always looked like it was going to hit you even though you knew it wouldn’t - but somehow you couldn’t stop yourself being frightened by the noise as it zoomed past, taking your breath away.

Then Dot picked up a slightly different noise, a kind of strange humming in the distance. They were definitely being sucked towards it!

Wizard and Mister Mouse seemed totally relaxed, but Dot felt just a bit scared. She gave herself a little shake and shook her head. She knew she was being silly - Wizard would never let her down.

Just as she was becoming a bit tired of the darkness of the cable tunnels, she saw a light twinkling up ahead and they suddenly landed and came to a stop. She was so close to Wizard she nearly tumbled right over him!

When she got up – and the ground she got up from was kind of soft but still firm, like a bouncy castle - Dot could hardly believe her eyes. She was in the middle of the biggest bank of machines and computers she’d ever seen. As far as she looked, there were endless corridors of whirring disks and flashing lights, every machine seeming to give out electronic dialling sounds. And the humming noise was louder than ever!

At the centre of all the computers was the sparkling shining light she’d seen. It was very bright, but somehow she could still look straight at it. It was coming from the biggest computer of all. This computer had an enormous screen, and on the screen was the happiest sunny face Dot had ever seen. The face turned to look at her - and gave her a great big smile.

Then it spoke and the ground literally shook under her feet, so deep and powerful was the voice coming from the giant computer.

“Hello!” it said, its smile wider than ever. “Now you must be Dot Com. Welcome! I’ve been expecting you!”
