Endless Ocean 2: Adventures of the Deep Cheats for Wii
To find the Pelago Crocodile, simply look through your telescope on the morning before a full moon.
To locate Apollo the Sunfish, visit the Deep Hole at night. The sunfish should be above the Mouth of Truth.
You can find the Ancient Mother Whale in Adventures of the Deep by following the instructions below:
First, you need to complete the main story mode. You also need to have located every whale and dolphin in the game. Following these steps, purchase a totem pole and complete it's quest.
You will then see a mirage on the beach by the totem pole. Complete some of the special requests and maps until you unlock a carving of the Ancient Mother Whale. This indicates that the Ancient Mother Whale is now available off the North Coast of Canada.
There is a Labrador that you can bring home as a pet in Adventures of the Deep. Simply look through the telescope at Nineball Island - the game will tell you about the dog being washed up on the beach at Gatama Atoll.
Go to the Atoll (the northeast of the map) to find the Labrador.
Go to Cortica River Upstream. Go to the area with vines growing in the corner when you can see your body. Go as close as possible to the wall and the vines and to the surface. Press A and there will be a Gap in the wall. When you go back in the water you can swim through the wall. You're free! The area is infinitely deep and if you poke your head out of the water you can see from outside of the game and look in. Your diving partner (if you came with one) will stare at the spot where you escaped and make attempts to follow you. Pull up the map and the arrow that shows where you are will point at a land outside of the river. Have fun!
If it doesn't work on the first time, try, try again.
