Wataru who came to "Ryuguland" like an amusement park where everyone can enjoy smiling. After receiving the hospitality of the staff, he was in a good mood, but he couldn't enjoy the tiger king alone, and complained to Wataru, "It's not the case when you're playing in a place like this."

Wataru was fascinated by the fun of Ryuguland, but he regained his sanity when he was cheeked by the Tiger King.
