You need to get the 3 dolphins to open the gate.
First, get into a tunnel and swim in the middle of the red dye.
With your red fins go and talk to the crimson dolphin, he’ll join you.
Then, swim down to turn the wheel- there’s a lot of yellow fumes coming off it. After that, talk to the circle dolphin (the grayish one), he’ll join you as well because you’re so cool!
Go to the entrance of one the tunnels and you’ll see a baby dolphin- a mover. Talk to him and follow him to then bump his mum a few times and she’ll join you.
The gate opened, get that superb golden harness, go down to the big shield, and sonar the shiny thing in the middle of it.
You’re now not only looking very good; you’re also through to the next level.
