Move The Rocks
Move the rocks around the aquarium by grabbing one of them (X + R trigger) and pressing left and right. You can actually move one of the rocks so that it covers the air hole. Eventually when he's big enough Seaman will help you move the big rock in the back which will drain the water in the tank.
Hypnotize Your Seaman
Focus on one of your "SEAMEN" and move your joystick in circles around its head, the "SEAMAN" will begin to follow the circling finger icon and become hypnotized and roll over on it's back after a giggle. If only this worked on your real life siblings.
"Japan=Good" "America=Stupid"
Try it yourself, Talk to your SEAMAN and say "JAPAN" it'll reply "GOOD". Next try "AMERICA" and it'll reply "STUPID STUPID".

Evolve Seaman Quickly
You can evolve your seaman in about 2 hours. He won't be the smartest little critter out there but it won't take you a month to get any results out of the game. First you'll have to run the game at least once to create a save on your VMU and lay the egg in the water. After putting the egg in the water you can turn off the game and then open the lid to your Dreamcast and turn the Dreamcast on again. You'll be taken to the interface of the Dreamcast. Select Settings and then choose the date. Advance your clock 2 days (never advance your clock more than 2 days at a time or you'll return to a dead Seaman). Return to your game and check on your Seaman, Leonard Nemoy will give you a briefing about the welfare of your creature. Play with your Seaman a little Increase his water temp, feed them and make sure they are warm enough and then save your game and mess with the clock again. Keep doing this until you've got your seaman to the desired age.
