Tickle 2 Seaman At Once

First, start tickling a seaman then when he is laughing and said stop it move the hand to another seaman and they will both be happy.

Move Rocks

Press X + R and press Left or Right when over a rock to move it.

Hidden Audio

Place the game disc in an audio CD player and play track two to hear a hidden message.

Hypnotize Seaman

Select a Seaman and move the Analog-stick in circles around its head.

Give Your Seaman A New Name

After naming your Seaman the first time, repeatedly ask "Do you love me?". Eventually, you will be able to change your Seaman's name.

Talking To Your Seaman

It is good to talk to your Seaman frequently. You need to teach them how to talk. Try to talk as clear as possible. Hold the A and talk into the microphone. The Gillman stage is the stage when it will first start to talk. Use these words when talking to your Seaman: Hi, Hello, Hey, No, Yes, Seaman, Fish, Fun, Play, (and more). Experiment, but do not call it bad name or it will become unhappy. Also, remember to feed it at least once a day.

Quick Evolution Into Gillman Stage

While playing the game, you will see a shell at the bottom of the tank. Keep tapping the shell until it starts to eat your newborn Seaman (Mushroomer's). After they are eaten, tap the shell more until the squid completely comes out. It will squirm, and eventually after tapping it enough, it will die and the baby Seaman will appear and will be in the next stage (Gillman). Hold A while talking into the microphone to speak to your Seaman.

Quick Evolve

Set the Dreamcast's system date ahead several days for faster evolution. However, the tank will also not be maintained for that amount of time.

Infinite Food

Note: This trick requires two VMUs. Start and save a new game using a second VMU. Connect this VMU to a VMU that has an ongoing game. Transfer the food from the new game to the ongoing game. Repeat this as needed for unlimited food.
