On the Submarine level, if you see an ''!'' over Dory's head, it indicates you should move or Bruce will catch you.
To keep away from Bruce keep rotating the Analog-stick. Kayla Keller.
Hint: Avoiding the diver
When the diver is after you, he will always try to grab you in the same few locations. Learn where these are and avoid them.
Hint: FMV sequences
When you complete a level or are at the middle of a level, you will see an FMV sequence from the movie Finding Nemo.
Hint: Getting past pillar of bubbles
On level 11, to pass the first pillar of bubbles make a special sound with the heads before the pillar by blowing them in a certain order. To learn the order, go back to the last wooden sign. Swim to the left of it, face it, and charge it. Then, blow into the heads in the order that the heads appeared on the sign.
Hint: Gold Starfish
Going though all the bubble rings, putting the colored pebbles in the correct colored holes, bouncing on all the things that bounce, winning the races, and destroying all enemies will earn you Gold Starfish towards bonus levels. Note: There are some timed levels and timed races; be as quick as possible.
Hint: Keeping up with Dory
To keep up with Dory, grab all the bubble rings.
The little blue krill will keep you from getting hurt. Collect as many as you can. The krill only protect you from things such as pufferfish and eels, but not from swift currents or mines.
Hint: Puzzle solution
During the Submarine level, there is a pipes puzzle you must go through. As soon as you get into the room with the puzzle, look at the back wall right behind the door to find the solution to the puzzle.
