This secret can be found on the Powers of Levitation level. To play dolphin
soccer against a warring Clan member, swim to the large central building
underwater. Circle around it until you find the Information Shard. Enter
the central structure here and head down the tunnel until you find an oval
door near the bottom. This passage is split up by several weird organic
doors that dilate when you get near them, allowing you to pass. Ignore the
side paths for now, just head down the tunnel until you reach the chamber
at the end. There is a Clan member here and a bubbler in the center of the
room. If you turn and face the entrance, you'll notice an oval section of
wall to the left moving slightly in the current. Swim through it to find
a secret room. Inside is a Stealth power-up. Grab it and head straight back.
There are a pair of yellow lights at the back of the room. Touch your nose
to the right one to be taken to Dolphin's World Championship, a soccer match
between you and a fellow Clan member.
Swim to the bottom of the sea, and go back up as fast as you can, now jump
out of the water, and hold back on the joystick. Ecco does a flip! Hold
it longer if Ecco is higher in the air.
Do the same as the flip, but do not hold back, instead hold the joystick
forward and Ecco will do a dive into the water.
While underwater, just hold the joystick forward or backward, and Ecco will
do flips underwater.
In the first level, find the three dolphins. Ask the coach dolphin if you
can play the game. When you play, the object of the game is to watch what
fish the coach wants you to catch. But you better hurry, because you go
against two other quick dolphins.
In the second level, find two dolphins that are together. They are playing
a racing game. Ask one of them if you can join in, and you will race around
the track they tell you.
Great White Shark Tip
When you are going against the Great White Shark, when he gets stuck in
the hole, use your charge ability over and over without changing directions.
You will beat him alot faster that way.
