Tuna has a peculiar habit of collecting dried seaweed from different parts of the ocean and using them as bookmarks in her library books. Each bookmark reminds her of a different adventure or a moment with her family.

When Tuna gets lost in her thoughts or is particularly focused on a task, she unconsciously hums melodies that mimic the sound of waves crashing or the calls of distant sea creatures. It's a calming presence in the library.

Instead of the traditional alphabetical order, Tuna organizes her library books according to the ecosystem or habitat of the creatures mentioned within. So, books about forest creatures would be shelved separately from those about ocean dwellers.

Tuna has a vast collection of shells displayed around her librarian desk. Each shell holds a special memory for her, whether it's a token from a family vacation or a gift from her wife, Mackerel.

Tuna's life revolves around routines and schedules. Every day begins with a cup of seaweed tea brewed just right and ends with a bedtime story for Angelfish, no exceptions.

Tuna has an uncanny ability to predict the tides accurately. She plans her outdoor activities and family outings around the ocean's rhythm, ensuring they coincide with the best fishing times for Mackerel.

In her spare time, Tuna enjoys sculpting intricate figures out of driftwood she finds washed ashore. These sculptures often depict scenes from her family's adventures or mythical creatures from folklore.

Tuna prefers to write with ink made from a special blend of saltwater and squid ink. The briny aroma and unique texture enhance her connection to the ocean even when she's indoors.

Tuna's library is adorned with wind chimes, mobiles, and hanging decorations that sway and chime with the slightest breeze. She believes they bring the tranquility of the ocean indoors, adapting to the changing weather outside.

Tuna has a knack for weaving fantastical tales inspired by her adventures with Mackerel and Angelfish. She often incorporates elements of nature and lore into her stories, captivating her audience with every word.
