Like all the gods, Poseidon loved being worshipped by the people.
But when the people started forgetting about Poseidon, he got very angry and decided he didn't want to be forgotten.
He came up with a plan so that the humans would never forget him. But he had to go to Zeus first.
Poseidon was going to send a hug wave at the towns near the water so that they would know he was the powerful one who controlled the water. He had to ask Zeus because the towns were his territory. Zeus said he could.
Go ahead my bro
Now whenever the people start to forget about him, Poseidon will send a huge wave to remind them that he is a god.
Oops Poseidon's mad I guess we should worship him more
