with their tails and flippers.
Gipsy looked at a plastic newspaper floating in the water
âThe Liopleurodon Times.
Itâs six years old!â she said. âThis ship has been down here for six whole years at the very least!â
âSo the ship crashed here a year before the cryptoclidus first arrived,â Teggs realized. âAnd the trouble only started when they started building factories around this area.â
âMaybe they disturbed something,â said Gipsy. âSomething dangerous!â Teggs nodded. Then he noticed a metal box on the floor with an aerial on top, half covered by the water. âHey, Gipsy! This looks familiar . . .â
âItâs for sending distress calls!â cried Gipsy. âWeâve got something like it on the
Sauropod
.â She looked closely at the box. âItâs broken. But maybe I can fix it!â
âTry!â Teggs urged her. âIf we could only send an SOS to Sea Station One . . .â
He waited anxiously while Gipsy went to work with her delicate claws. Finally she gave a small hoot of success. âI think Iâve got it working,â she said. âBut thereâs not much power. The signal is very weak.â
âSomeone will hear it,â said Teggs quietly. âThey
must
.â
With nothing to do but wait, the astrosaurs moved on into the cold shadows of the creepy ship.Meanwhile, back on Sea Station One, Iggy and Arx were hard at work down in the storeroom. The two of them had been waiting ages for news of Teggs and Gipsy. They were worried sick.
Arx was still checking over the chewed-up wreckage. He was patiently comparing sections of sub, fragments of floating factory and bits of the diving bell.
Iggy had talked some cryptoclidus sailors into helping him fix one of the broken subs. They were busy in the room next door, hammering out dents in the subâs metal body and fixing all the instruments. Iggy himself had taken tiny pieces from all the subs and was using them to build a brand new engine. Now it was ready for testing, so he switched it on.
With a gentle hum, the engine started up first time.
âIâve done it!â cried Iggy. âThis new engine is ten times better and fifty times quieter than the old ones!â
Then the door to the storeroom flew open as Cripes splashed inside. Arx and Iggy spoke together. âWell?â
âThe search party canât find a thing down there,â said Cripes. âBut every radio in the place is picking up some kind of weird SOS call! It seems to be coming from somewhere
beneath
the sea bed!â
âIt
might
be Teggs and Gipsy,â cried Arx.
âIf they are down there, Iâll find them!â vowed Iggy. âMy new super-sub is almost ready to go. And itâs fitted with all kinds of extra gadgets!â
âBut we know that the liopleurodon has a taste for subs,â Cripes reminded him. âIt chomped all the old ones to pieces!â
Arx cleared his throat. âActually, thatâs not true.â
Cripes and Iggy stared at him.
âIt was not a liopleurodon who chomped up the subs,â he went on. âAnd it was not a liopleurodon who wrecked those floating factories.â
âCome on!â Cripes scoffed. âYouâll be telling us next that a liopleurodon didnât chew up that diving bell.â
âOh, no,â said Arx. âA liopleurodon
definitely
did that.â He nodded. âThatâs how I know it didnât do anything else!â
âHow?â asked Cripes.
âTooth marks!â cried Arx. âLook at that diving bell. It was ripped apart by long, sharp teeth. You can see the marks from here.â
âSo?â said Iggy.
âSo, I havenât found tooth marks like that anywhere else,â Arx said.
âNot on
any
of this wreckage.â
âWhat
did
you find?â asked Cripes.
â
Tiny
marks,â Arx told him. âHundreds
