As a Jay Leno-esque, Chinny McStrongchin looking character, you are off to explore the depths of the ocean with hopes of finding Atlantis. Let's go!
On my first adventure I fought a ginormous squid, discovered an ancient Greek ship upon which was a map showing a tunnel to the center of the earth. I entered the tunnel and soon the water turned to gas and I had to dodge massive atoms. The world became a shade more psychedelic. Undefined presences surrounded me as I entered a thought world. I'd found Atlanteans! I stayed with them, studying for 1000 thought years and emerged to find the surface of the world quite different from when I left it.
On the next adventure I was quickly eaten by sharks.
I had another go, got saved by a dolphin (at this point I've noticed that there are a number of ways in which this book allows you to just give up), found and entered a grotto, which turned out to be Atlantis! I got a species-change operation and never returned to the surface again.
In my final adventure I took my little underwater craft down into a canyon, where I found another grotto and a submarine. Inside the sub I received instructions on how to get to Atlantis. I met some folks, tried to help them overthrow a tyrannical king, and in order to do so I suggested we put on a play, naturally. In a roundabout way it worked!
There are a bunch more endings, all of which look WAY more exciting than my adventures, if the illustrations by Paul Granger are anything to go by. There's some kind of wacky castle pool type thing, cyclones, whales, dudes wearing Kaiser helmets shooting lasers, a ghoulish scientist and more. If I'd come across any of that, this book would easily be four stars, maybe five!
