Going into a building made by a squid is risky. First of all, squids only have tentacles, no bones, and they make all of their buildings out of risky materials like kelp and sharp coral.
"It's too risky, leave me!" the squid cries. "I'll save you, underwater citizen! Nothing is too risky for Ken (けん) the samurai!" The building is collapsing on the squid, the risk is so great, but Ken the samurai dives in and saves him!
