Get past Bruce on level 9
To get past Bruce when he is chasing you swim to the top and than look at Dory. When there is a mark on her swim down to this repeatedly to get past Bruce.
Keeping up with Dory
To keep up with Dory, grab all the bubble rings.
Upon finishing a level or are in the middle of a level, you will see an FMV sequence from the movie Finding Nemo.
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.
Whenever you are trying to solve a slide puzzle, its best to start from the top first. You can keep sliding and solving the puzzle from left or right as you work your way down from the top.
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.
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.

On the level 7 (the Submarine), 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.
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.
Submarine Slide Puzzle Map
When you enter the door to the first slide puzzle look in the background and you will see a MAP. Copy it down on paper and follow it for the solution to the puzzle.
Tip for Level 7 (submarine)
OK, you made it this far, and you might be stuck on something. While you think about that, try doing something else. Do a bonus thing. In this case, it's the pebble game. You know, where you have to match the red, blue, and green pebbles to their bowl thingies. Here's the tip. After you run away from Bruce twice, There are a couple broiler rooms. (After you run away from him once, there is only one broiler room.) There is the first room, there are NO pebbles in that room. The second room is different. Right when you enter that room go low towards the ground. You should see the red bowl. Ignore that for now, but remember that now. Explore a little bit more, and you will find the green pebble. Carry it until you find the green bowl. (There should be the red and blue pebbles there also.) Drop the green pebble in the bowl, the pick up the red one.
Now go back to the beginning of the room, and remember that red bowl? Well, find that, and drop the red pebble in. Go back to the green bowl, and pick up the blue pebble. The blue bowl isn't until the next broiler room. The blue bowl is at the top of the ceiling, in the next broiler room. Explore to find it. Well, that's it! You should get a starfish for your hard work.
To get past the chain at the end of the submarine level... you need to smack the green arrow button REALLY HARD. It took me ages to figure that one out
