Go to the Powers of Levitation level. Once there, swim the large central building underwater and search around it until you find the Information Shard. From there, enter the central structure and cruise down the tunnel until you find an oval door near the bottom. Head through the passage which is split up by doors that dilate when you get near then so that you can pass through them. Ignore the side paths and just head down the tunnel to the chamber at the end. Inside is a clan member and an air producer in the center of the room. Turn and face the entrance and you'll see an oval section of wall to the left that's moving a bit with the current. Swim through it and you'll find a secret room--inside is a Stealth power-up. Grab it and head straight back, and you'll find a pair of yellow lights at the back of the room. Touch your nose to the right one and you'll enter the soccer room.

This secret is found on the Powers of Levitation level.

To play dolphin soccer against a warring Clan member, the first order of business is to swim to the large central building underwater. Circle 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 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 Clan member.
