Crystal of The Sea

Crystal of the Sea is a local Indonesian premium snack brand for kids. The project was a collaboration with Pinkfong, the global kids entertainment brand best known for Baby Shark and one of the most recognised properties in the children's content space.

Brand collaborations in the kids category are their own kind of design challenge. Two brands meeting on the same packaging, two visual systems that each carry their own equity, and an audience (kids and the parents buying for them) that decides in seconds whether the product is worth picking up off the shelf.

The brief was specific. Integrate Pinkfong's brand world into Crystal of the Sea's product packaging without either side losing its identity. Make it land for kids. Keep it visually appealing enough that parents pull it off the shelf.

In a collaboration like this, the easy mistake is to let one brand swallow the other. Pinkfong is loud and recognisable, with a strong colour system and instantly known characters. Crystal of the Sea has its own identity as a premium snack brand and could not afford to disappear behind a licensing partner. The packaging had to feel like both brands at once, not like one brand wearing another's costume.

Add the kids audience constraint on top. Kids do not read product copy. They look at the packaging and react. The visual system has to do the work in the first second of contact.

We treated it as a genuine integration rather than a sticker job. Pinkfong's character world got woven into the packaging illustration system in a way that felt native to Crystal of the Sea's premium positioning. Colour, layout, and typography stayed grounded in the parent brand. The Pinkfong elements lived inside that system, not on top of it.

For kids appeal, the illustration approach leaned into a friendly, playful direction without going cheap. There is a real difference between premium kids packaging and generic kids packaging, and most of it lives in the small details. Line weights that feel hand-drawn rather than templated. Colour palettes that are bright but considered. Character placement that gives the packaging energy without making it look chaotic.

Deliverables included the full collaboration packaging system across SKUs, illustration work that integrated Pinkfong characters with the Crystal of the Sea world, supporting visual assets for retail, and the print-ready files.

The two brands blended naturally. Crystal of the Sea kept its premium positioning. Pinkfong's recognisability did its job at shelf level. Kids saw characters they knew. Parents saw a product that looked elevated rather than generic. For a kids FMCG collaboration, that combination is what makes it commercially worth doing.

For a creative partner running a project like this, the hard part is holding the balance. Lean too far into the licensed property and the packaging looks like merch rather than food. Lean too far into the parent brand and the collaboration loses its commercial reason for existing. The work landed in the middle on purpose.

This case study covers brand collaboration design, illustration for the kids category, FMCG packaging design in Indonesia, and the operational side of working across two brand systems at once. For F&B and snack brands looking at branding agencies in Jakarta with experience in licensed collaborations or kids products, this is one example of how that engagement runs.

Kids packaging is one of the more competitive categories in retail. Shelves are dense. Brands compete with their loudest visual cues. The temptation in a Pinkfong collaboration is to crank up every element and hope volume wins. The smarter move is to let the recognised characters do their job while the rest of the packaging stays disciplined.

Crystal of the Sea ended up with collaboration packaging that does both. It reads as Pinkfong from across the aisle. It reads as a premium snack brand once you pick it up. Both readings hold up at the same time.
