suddenly, the whole passageway started to shake.
âLook out, Dippa!â shouted Teggs. âThe walls are caving in!â
âEeek!â squeaked Goopo. He turned and fled, his brothers close behind. Teggs and Dippa huddled together as big speckled slabs kept on falling. Soon the passage was completely blocked. They were safe from the oviraptors â but now there was no way back to the
Sauropod.
âThereâs only one path we can take now,â said Teggs quietly. âBut itâll lead us right to whateverâs been making that terrible noise!â
Meanwhile, Gipsy and were huddled outside in a howling gale, wishing they were warm and safe back on the
Sauropod.
Like Teggs and Dippa, they had hidden in one of the great splits in the planetâs surface. But the ledge they were creeping along was very narrow. One slip, and they would fall to their doom.
âI wonder what caused all these cracks,â said Sog nervously. âIf it was an earthquake, whereâs all the rubble? Thereâs not a single loose stone round here!â
âMaybe itâs special, super-tough rock,â said Gipsy. âThatâs why the explorersâ seeds never grew.â Gipsyâs tracker started beeping loudly. âYou know, this thing is going crazy. It reckons the source of that signal is . . . everywhere!â
âShhh!â gasped the little professor. âI think somethingâs coming!â
He was right. Something heavy was creeping along the ledge in the opposite direction â straight towards them.
âItâs too dark!â hissed Gipsy. âI canât see what it is!â
âItâs the thing that made that terrible wailing noise!â cried Sog. âI know it is!â
He hopped onto Gipsyâs tail and scampered up to her shoulder in fright.
The footsteps shuffled closer and closer . . .
Chapter Eight
THE SECRET OF PLATUS TWO
âHalt!â squawked Professor Sog bravely. He peered out from behind the crest on Gipsyâs head. âWho goes there?â
A familiar figure came out of the shadows. âHello, Gipsy! Professor!â
âArx!â squealed Gipsy in delight.
âAnd me!â called Coo from somewhere behind him.
âThank goodness!â gasped Sog. âSo, you hid in the crack too!â
âThere was nowhere else to go,â said Arx. He seemed a little out of breath.
âIâm glad weâve found you. Thereâs something I think you should see.â
âWhat is it?â asked Gipsy.
But Arx was already retracing his footsteps. âThe path gets very steep down here. Donât slip!â
Gipsy and Sog followed them along the ledge. Arx was right â the path dipped down sharply. Gipsy trod carefully, while Sog slithered down on his bottom.
The air grew warmer. The ledge grew wider. A soft, thudding noise seemed to echo up from the chasm beside them.
To Gipsy, it sounded like a huge,heavy heartbeat. Her tracker bleeped so loudly she had to turn it off.
They crept on for what felt like ages. Then, suddenly, the steep path levelled out. Arx came to a sudden stop.
âHere we are,â he said. âA hole. I think it stretches down to the very centre of the planet!â
Gipsy stared down into the hole. This was the source of the heartbeat sound:
Ba-DUMP
. . .
Ba-DUMP
. . .
Ba-DUMP
. . .
It was like looking into a deep well. Far below, thick yellowy-white liquid sloshed about like runny custard.
âKeep watching,â Arx murmured.
Then, just below the slimy surface of the goo . . . something massive moved!
âWhat was that?â Gipsy gasped.
âI think I know,â said Arx. âBut if Iâm right, weâre in worse trouble than we thought!â
Even as he spoke, the wall behind them exploded with a mighty crash!
Coo yelped as bits of the strange, smooth rock flew through the air. Sog hid behind Arxâs head for safety.
