Mythology island
The offering for Poseidon is a starfish. There is one on the face of his statue in the Museum of Olympus.
Go to the Temple of Hades and place the pomegranate on the 'offering shrine'. Then you'll find yourself next to the River Styx where you can proceed on your way to Cerebus to get Cerebus' whisker.
when you go into the museum on mythology island, go right and you will come to a hall that tells you all about the gods. when you reach posiden's statue, there will be a huge pink starfish sticking to his face. this is posiden's offering.
to get it you have to get near the tree next to the water
