Jungle Island

The first eye orb is on the wall just outside of the cave from the Mag-Lev Station.

It sounds like a monkey crying or a squeeky door.

The symbol for the number 3 is engraved on it.

On entering Sunner's Lagoon, listen to the sound that the sunner's make.

Around the back of their rock is an eye orb.

It sounds like blowing on a bottle or a whale call.

The symbol for the number 5 is engraved on it.

Going toward the Fire Marble Dome, there is a gate with a beetle on the side. Look closer and listen to the sound he makes.

Heading toward the submarine, there is another eye orb.

It sounds like some sort of mechanical hum or a rubberband strianing.

The symbol for the number 2 is engraved on it.

The sound is similar to that of the beetle. Turning the knob, water fills the tub and a symbol for the beetle appears.

The next eye orb is off the path to the Fire Marble Dome (where the large stone knife can be seen to the side of the path).

It sounds like some sort of mechanical hum or a rubberband strianing.

The symbol for the number 4 is engraved on it.

Continuing inside the Fire Marble Dome take the path to the right toward the Whark Idol.
