Kai went into his bedroom. He went up the ladder. Then he climbed out onto the deck. The deck had a glass roof. And two glass walls. One wall was made of brick.

On the brick wall was a big photo of the beach.

Kai pushed a button on the wall. The photo slid down. A big touch screen was hiding behind the photo.

Kai touched ‘roof open’ on the screen.

The glass roof slid open. Next he touched ‘wind sock’. The wind sock came out from the wall. It went up into the air. It filled with wind. Then the wind sock closed. Then it came back inside.

Kai touched ‘roof close’. He took the wind sock. Then he went to the kitchen. BC was waiting for him in the pantry. ‘Can I push the secret button?’ asked BC.

‘Go for it,’ said Kai as he looked for something to eat. No snacks for me to eat here. I’m so hungry, he thought. I wish I’d had time to eat my burger.

BC pushed the button with his nose. It was under the pantry shelf.

The pantry’s back wall started to move. It slid open. Kai and BC went in behind the wall. They went down the ladder into the lab. It was under the kitchen.

The lab was filled with top-secret tools. Tools for learning all about beasts.

Kai put the wind sock into the sample tester.

He hit the test button on his computer.

‘Rock and air lands,’ said Kai. ‘Yes. Dirt and wind.’

‘We battle rock beasts again?’ asked BC.

‘No,’ said Kai. ‘I think it’s the air land. The wind goes in circles. Just like in the air land, Tornados.’

Kai hit the air land button. I hope I’m right, he thought. Then the computer flashed again. A card popped up on the screen.

‘This beast looks mean,’ said Kai. ‘Let’s go get our battle gear. This will be a hard battle.’
