Deep under the sea, there was a dark cave that nobody visited. In that cave lived an octopus named Ollie, who was very shy and afraid of everything. He had eight arms, but he often hid them under rocks because he felt safe that way. One day, a strong current pushed him into a strange tunnel that led to a dry place. When he looked up, he saw a huge pyramid that was older than the sea itself.
Ollie was scared, but he was also curious. He moved slowly into the pyramid, and his eight arms touched the cold stone walls. Inside, there were paintings of sea creatures that glowed in the dark. Suddenly, he heard a small voice that said, "Help me, please!" It was a little crab named Cleo, who was trapped under a heavy stone. Ollie wanted to run away, but he knew he had to help.
