Since its debut in 2018, the Australian children's TV show Bluey has garnered widespread acclaim, distinguishing itself as a premier program in its genre.

In 2019, a year after its initial launch, Bluey expanded its reach globally through Disney.

The show swiftly gained popularity, enchanting both children and adults alike.

Bluey focuses on the adventures of a seven-year-old blue heeler dog named Bluey, and her five-year-old red heeler sister, Bingo.

The narrative is enriched by a varied ensemble of their friends and family.

The episodes typically feature the sisters immersed in creative play, using their imaginations to embark on various adventures and learning important life lessons along the way.

Every episode runs for approximately seven minutes.

Having completed three seasons with over 150 episodes, Bluey has been praised for its high-quality children's content and its commitment to inclusivity, notably highlighted in the final episode of the third season.

In the most recent episode of the series, Bluey subtly introduces its first same-sex couple.

In the episode, Pretzel, a chihuahua friend of Bluey's, casually mentions his family structure while talking about his pet guinea pig.

He shares, "When my guinea pig ran away, my mums told me he might come back, but he didn't."

This dialogue is part of the 28-minute season finale called "The Sign," which is notably four times the length of a regular episode.

While the mention of a same-sex couple is brief, it represents a significant step forward in LGBTQ representation in children's television.

A fan shared their excitement on X (previously known as Twitter), stating: "Pretzel having lesbian moms still makes me happy. Bluey pulling out the representation."

Others have expressed the personal significance of this moment.

On the platform owned by Elon Musk, another user commented: "As a person who lived with his mom and her gf at one point in time, I think this is great."

However, the inclusion of a same-sex couple has met with mixed reactions.

Critics have labeled it as contrived and superfluous.

Nevertheless, the controversy has not impacted the episode's success.

As of now, "The Sign" is the highest-rated episode of Bluey on IMDb, boasting an impressive 9.9 out of 10 just four days after its release.
