“The fourth M thing must be out there,”
said Annie. Beside the door was a button
with the word OPEN on it.
Annie reached for the button.
“Wait!” Jack grabbed her hand.
“There’s no air on the moon. Remember?”
“Oh. Right. But we have to go out to find the M thing.”
“Let’s see what the book says,” said Jack.
She stood at the edge of the crater.
“What is it?” said jack. “ A moon buggy!” said Annie.
The buggy was parked in the crater. It had four huge wheels.
“Let’s go for a ride,”said Annie.
“We can’t,”said Jack.
“We just have two hours of air in our tanks. Remember?”
“I bet we’ll find the M thing faster if we take the moon buggy!”
Annie bounded into the crater.
