There are three hazards to avoid, and you will face them 4 or 5 times :
There are usually 3 sets of hazards on the River Styx, each set consisting of one rock fall, one flaming skull, and one river monster.
The River Styx on Mythology Island is not explicitly mentioned in terms of its specific length. However, in Greek mythology, the River Styx is said to encircle the Underworld multiple times, so it can be inferred that it is a vast and lengthy river.
Go find the Pomegranates. Go to the Grove of Temples. Then, continue going left until you get to Hades Temple. Go into his temple, and place the pomegranates on the offering podium. Go into the door and fall and fall. You will get to the river Styx. Go to that.
Move from left to right (back or forward in the boat) to dodge the rocks. jump high to avoid the flaming skulls. Jump to avoid the river monsters. Normally there are 4 or 5 sets. If you fall out of the boat, you must start over.
If they were mortal, they would fall in and die, unless they were trying to become invincible like Achilles. If they were dead, they couldn't get into the underworld without being ferried across the Styx.
In the underworld .when you get to the under world you'll have to ride the boat in river Styx. while riding you have to duck down for fossil or move to the left or right it will try and hit you , also watch out for the skulls they will hurt you to.if you fall into the river you'll have to start over.
Cerberus is in the underworld. You get to him by going on the boat ride across the river. But you have to watch out because if you fall in you have to start all over again.
First get the flute, or reed pipe, and learn the tune to put Cerberus to sleep. Then get the pomegranate's, offer them in the temple of Hades, fall down the abyss in the next room, get a ride across the River Styx's, play the tune on your flute, and grab the whiskers.
The entrance to the Underworld (realm of Hades) is in the Temple of Hades. Put pomegranates (from the garden of the Sphinx) on the altar to open the door. The only path to the River Styx is a vertical fall into the bottomless pit. Cross the river and get a whisker from Cerberus by playing the reed pipe (blue-green-yellow-blue-red-green). You cannot enter the Hades throne room until later when Hercules is helping you.
If your talking about on mythology island, you go up the rope to the left that as a sign that starts with an A. climb that and mess with the wheels.And when you get them all right,it shows the water start to fall.
Play the song one of the Muses gave you and he will fall asleep.
Play the song the muse gave you on the pipe.
