Fins flailing, water surging behind him, Seaking charged into the rock at the edge of the lake, drilling a hole into it with his long horn.
“There! Done.” Seaking swam to the surface. “I made a hole for us to hide the egg in until it’s ready to hatch.
Wailord peered at the hole, no wider than one of her fins. “That’s great, sweetie, but…” She looked to the side. “Do you think the egg will fit?”
Seaking looked at the egg. It was about as big as Seaking.
“Hmm, it might be a tight fit.”
