On Jungle Island after visiting the school, park your mini sub at the closest opening towards the lower entrance of the city (you should of already seen the parent come grab the kid as you were walking in- if you entered that way) get out of the sub and take the path leading up the ladder towards all the living huts. At the top of the ladder you will be in front of the only hut that has a ramp leading to the door. If you notice on the door knocker is the #5, which is what you just learned from the fish game. Knock 5 times (consistantly!) and a little boy will open up a tile on the door and look at you, then shut it again. Dont blink or you'll miss it! it kinda freaked me out!

When you go to open the fish head for the first time (the button on the right lamp when you're facing the fish) walk all the way into it, turn around (like you've changed your mind) and walk back out. Dont touch any controls! keep on the trail and as soon as you turn right there's a little girl who turns to run and trips over herself, she gets back up and runs away. Now I dont know if you can touch any controls, or take the back way to the island through the mouth. All I know is that I had left the island already and came back. I was stuck and found the entrance button by mistake and decided not to go that way just yet! and ended up finding the little girl spying on me.
