have to do whatever it takes. Go wherever we need to go. This is the most important bum hunt in history! If we can catch this bum, there wonât be any need for anyone to catch a bum ever again. Without the Great White Bum inciting bums to rebellion, bums across theunivarse will be able to work with their bodies instead of against them.â
âBut I work with you,â said Zackâs bum.
â Now you do,â said Zack. âBut it hasnât always been that way, has it?â
Before Zackâs bum could reply, Robobum suddenly turned steeply.
âChanging course,â said Robobum.
âOuch!â said Zack as he lost his grip on the navigator and fell face first against the bumcam screens. The other bum-fighters fell right on top of him, powerless to resist the intense B-forces unleashed by the dive. Zack could see that the tiny white bum was now heading back towards the ground. But not for long.
Zack was close to blacking out when Robobum changed course again. This time the bum-fighters fell hard against the back wall.
Then Robobum changed course again.
And again.
And yet again.
The bum-fighters were being thrown around like dirty socks in a washing machine.
Zack felt his head smash against something hard.
There was a huge crash.
And then silence.
CHAPTER 25
65,000,000 BC
âO UCH!â said Robobum. âThat hurt!â
Inside Robobum, her hapless occupants lay on the floor and blinked stupidly at one another.
They tried to remember who they were.
They tried to remember where they were.
They tried to remember why they were where they were.
Zackâs bum was the first to fully reorient itself.
âZack!â it said, jumping onto his lap. âWake up!â
Zack looked at his bum dumbly.
âPleased to meet you,â he said, extending his hand. âMy name is Zack.â
âI know who you are!â said his bum, slapping Zackâs hand away. âItâs meâyour bumâremember?â
Zack tried to focus on the small pink excitable bum in front of him. It looked familiar, but he was having a lot of trouble remembering why.
âYou look like somebody I know . . .â said Zack.
âMaybe this will jog your memory,â said his bum, huffing in Zackâs face.
The obnoxious odour sent Zack into a doubled-over coughing fit, but when heâd come to, he remembered exactly who he was. And exactly who it was.
âWhy, you . . .â he said to his bum, reaching out to strangle it.
âSteady, Zack,â it said, jumping out of the way. âYou were delirious. I had to do it. Iâm sorry.â
âNot as sorry as I am,â said Zack, stifling another coughing fit. Beside him, Eleanor and Ned were coughing and returning to their senses as well.
Zack rose to his feetâa little dizzy from both the bad air and the blow to his head. He staggered to the bumcam screens.
He could see that they were in a lush bumnut-tree forest. The bumnut trees were enormousâtaller than any he had ever seenâtheir thick brown fronds blocking out the sky.
âI donât believe it,â said Ned from behind him. âI donât believe it!â
âWhat?â said Zack.
Ned was bent over the temporal navigator. âI donât know how this has happened, but the temporal navigator indicates that we are deep in the heart of the late Cretaceous period.â
âWhat does that mean?â said Zackâs bum.
âItâs 65 million years BC,â said Ned, still shaking his head in wonder.
âYou mean we just travelled through time?â said Eleanor. âForwards?â
âIt would seem so,â said Ned, scratching his beard. âIt appears that weâre exactly where we need to be.â
âThanks, Ned!â said Eleanor. âYouâre a genius!â
âI didnât do anything,â said Ned. âThank Robobum!â
âThanks, Robobum,â said
