Somebody mentioned this in the comments, and here it is. A three dollar bill from the Cook Islands

 

The Cook Islands $3 bill, featuring the iconic image of Ina and the shark, is a unique collector's item and has been in circulation since 1987.

The Cook Islands $3 note is notable for its artistic design and cultural significance. It depicts Ina, a character from local legend, riding a shark, which symbolizes her journey in search of her lover, the ocean god Tinirau. This imagery is derived from a painting by the late artist Rick Welland, who lived in the Cook Islands and created the artwork that inspired the bill's design.

The Reverse:

This is the design originally issued in 1987.  There is a modified version issued in 2021.  In my opinion the 1987 version is better.

The Cook Islands are a self-governing country that is freely associated with the New Zealand. It contains fifteen islands and has land and ocean combined.
