Geordie Racer/The caves on the beach

At the start of this challenge, the text "Quick, Baz is getting away in his boat. Search the caves to see if you can find something to help you." will appear at the bottom of the screen; once you have pressed Space to continue, the game will ask you "Which cave would you like to visit?" with three options (Quiet, Noisy and Smelly) below it. Every time you visit a cave, Baz will row forward in his boat - and if you visit the quiet cave, the text of "This cave is quiet because nothing much lives in it." will appear at the bottom of the screen. Once you have pressed Space to continue, the text of "There is a red herring here. Do you want to take it?" will appear, at the bottom of the screen; if you answer "Yes", the game will say "That doesn't help!". If you visit the smelly cave the text "This cave is smelly because it is full of seaweed." shall appear at the bottom of the screen - and if you visit the noisy cave, the text "This cave is noisy because a lot of bats live in it." will appear at the bottom of the screen. Once you have pressed Space to continue, the text "If you can tell the bats what is in the smelly cave, they will help." will appear at the bottom of the screen as a cursor flashes on the line below it; once you type in SEAWEED the text "Good. They give you a SILVER SPADE." will appear at the bottom of the screen. You'll now have to visit the smelly cave again - and once you've done so, the text "You dig up the seaweed with your SILVER SPADE." will appear at the bottom of the screen. Once you have pushed Space to continue, the text of "You find SAL the SEA SERPENT. She will help you to catch Baz." shall appear at the bottom of the screen; once you press Space to continue, the game shall proceed to the tenth challenge, and you must help Sal through the rocks without letting her crash into them.
