Resorts World Sentosa (RWS) is turning Sanrio’s half-fishman character Hangyodon into Southeast Asia’s largest immersive brand experience with “Hangyodon marine discovery” at Singapore Oceanarium. Running from 28 November 2025 to 4 January 2026, the activation marks Hangyodon’s 40th anniversary and blends playful engagement with environmental education.
As part of the campaign, visitors follow Hangyodon and his friend Sayuri the octopus on their first ocean adventure, exploring interactive installations that highlight marine conservation and the impact of pollution on aquatic life. The experience combines storytelling, photo opportunities, and hands-on activities to create a multi-sensory journey for fans of all ages.
Highlights include life-size photo moments, themed collectibles and F&B, a giant inflatable installation at the entrance, and guided programmes such as ‘Animal spotlight: Corals’, offering behind-the-scenes access to Singapore Oceanarium’s animal care operations.

Meet-and-greets with Hangyodon mascots further drive engagement, turning the event into both a marketing and educational platform.
“Through his cheerful and quirky world, we hope to make learning about the ocean a joyful adventure,” said Lam Xue Ying, acting senior vice president of Singapore Oceanarium & destination experience.
“This collaboration channels Hangyodon’s boundless joy into a shared love for the ocean – inspiring fans and guests alike to care for the blue planet we all depend on,” she added.
In tandem, Kohei Imai, COO of Sanrio SEA, added: “Hangyodon has always combined humour with heart. This collaboration allows fans and visitors of all ages to experience his world in a way that is both enjoyable and purposeful.”
The event positions Hangyodon as both an entertainment and purpose-driven IP, reflecting a growing trend of brands using beloved characters to drive engagement, footfall, and social conversation, while integrating education and sustainability messaging.
The “Hangyodon marine discovery” activation builds on Resorts World Sentosa’s major rebrand of S.E.A. Aquarium into the Singapore Oceanarium, which reopened on 23 July 2025.
The transformation marked a strategic shift from a traditional marine tourism attraction to a purpose-led edutainment institute, tripling the facility’s footprint and centering its mission on marine conservation, research, and education. With 22 thematic zones, flagship exhibits such as ‘Ocean wonders’ and ‘Ancient waters’, and immersive storytelling at scale, the Oceanarium has positioned itself as a regional leader in science communication and ocean stewardship.
