Franklin Jonas and Noah Cyrus got a small matching tattoo of Ponyo and Sosuke on their inner forearms. It’s a movie reference with a direct link to Jonas’s own work.
The matching Ponyo and Sosuke tattoo

Each inner forearm has the same small black-outline scene: Ponyo and Sosuke leaning toward each other. The caption accompanying the reveal translates as “Ponyo loves Sosuke.” There is open skin around the figures, so the faces and simple lines have room to read without a lot of shading.
Why the reference matters to them
Each forearm carries the complete scene, so neither tattoo needs the other to make sense. The shared image connects them without adding initials or a date.
The Ponyo connection
Jonas voiced Sosuke in the English-language version of Ponyo. In the film, Ponyo is a magical fish who wants to become human; she and Sosuke look after each other as the story unfolds. The tattoo chooses one small moment between them instead of trying to summarize the whole film.
A clear gesture or expression often carries more than a crowded scene. An artist can simplify the background or small details so the characters stay recognizable at tattoo size.

This portrait of Jonas and Cyrus provides context; it isn’t evidence of the tattoo. The close-up above shows the ink itself.
Franklin and Noah before the new drawing
Jonas and Cyrus have known each other since they were young. The movie reference sits within that longer history without spelling it out on their skin.

A matching tattoo can mark a shared history without needing to explain every part of it.
Franklin’s style outside the reveal

This graduation portrait is also contextual, not proof of another tattoo. The Ponyo design’s inner-forearm placement gives it room while letting Jonas cover it with a sleeve or show it by turning his arm. Since the forearm rotates, an artist should check how the image looks from different angles.
Keep the line work simple and give two faces enough space to stay clear. Ask to see the design at its actual tattoo size; a frame that looks detailed on a screen may need to be simplified for skin. Follow the artist’s aftercare advice and protect the tattoo from unnecessary sun while it heals.
