The Seal-Queen pointed the way, and soon Selina, with a few brave Selkie companions, was off. They swam deeper than Selina had ever imagined, past strange glowing creatures and forests of swaying kelp. The water grew darker, and the coral, once so vibrant, was now a dusty grey. A chill ran through Selina, but she pressed on, her heart full of purpose.
After a long swim, they arrived at a cavern, dark and imposing, guarded by jagged rocks. From inside, they could hear a low, rumbling sound. 'That's him!' whispered a little Selkie, trembling slightly. Peeking around a shadowy corner, Selina saw him. 'My word, what a sight met their eyes when they reached the entrance!'
The Giant Crab was enormous, with a shell as rough as a mountain and claws the size of small tree trunks. His eyes glowered from stalks, swiveling back and forth, always watchful. He looked ever so grumpy, with a permanent frown on his ancient face.
