The Axe
One of my favorite little details in Terraria is the Eye of Cthulu showing up in the background, flying through the night sky. It's a fun little easter egg that adds to the nighttime atmosphere, but why is it the only boss that shows up? It would be amazing if other bosses appeared in the background that teased your next fight. Bosses that could be added as background objects include the Eater of Worlds while in the Corruption, the Brain of Cthulu while in the Crimson, the Queen Bee while in the Jungle, the Mechanical Bosses at night in Hardmode, Queen Slime in the Hallow during the day, the Empress of Light in the Hallow at night, and Duke Fishron peaking out of the Ocean in Hardmode. Another detail could be the Moon occasionally phasing Post-Golem with the same effect as Void Dye, hinting that something on the Moon is growing restless.
