[8] Originally targeted at the preadolescent market, Gudetama gained popularity among teens and adults for embodying the difficulties of surviving in modern-day society.

Airplanes and trains have been branded with Gudetama themed decor, and restaurants have served Gudetama-themed egg dishes.

[1][2] The creation of Gudetama was inspired by an egg she was using to prepare tamago kake gohan for dinner after a long day at work.

[citation needed] In 2013, Gudetama took part in a food-based competition held by Sanrio to inspire its designers and test out new characters.

[16] The name "Gudetama" is derived from two parts: the first is the ideophone gudegude (Japanese: ぐでぐで), which is used to evoke the impression of something lazy and lacking energy.

As for its art style, Gudetama is marked by its simple line drawing, in keeping with the intention of using the character in anime for children, but which also allows easy mass production.

[9] The first Gudetama animated series made its debut appearance in 2014 in a Japanese TBS TV program called Asa Chan!

Shakipiyo (Japanese: しゃきぴよ) is a chick covered with yellow feathers and wearing an egg shell as pants.

Hardboiled (Japanese: ハードボイルド) is an egg character that is cooked as its name suggests, after boiling in hot water for more than 15 minutes.

[26][9] Translator Matt Alt commented that "using mascots such as Gudetama is a more nuanced way of expressing oneself than simply verbalizing an emotion or typing it out".

The series' short segments end with a rendition of the Gudetama theme song and a contemporary style dance performed by Nisetama-san.

A live action/CG animation hybrid television series called Gudetama: An Eggcellent Adventure was released in December 2022 on Netflix, with a total of 10 episodes.

[12][27] Shunsuke Takeuchi (Roger Craig Smith in the English dub) provides the voice for 24 different egg characters in the series, including Gudetama, while the voice of Shakipiyo is provided by Seiran Fukushima (Colleen O'Shaughnessey in the English dub).

[31] Originally targeted at a preadolescent audience, the Gudetama market has expanded to include millennials, with exports to many countries such as China, Singapore, the UK, and South Korea.

Within two years after the introduction of Gudetama, Sanrio has shipped nearly 2000 kinds of themed products in Japan, from pencils to suitcases.

In 2014, Village Vanguard Diner Lumine Machida opened a limited time Gudetama-themed café, offering themed cakes, burgers, pudding, etc.

[33][34] In 2016, Shoryu Ramen created a limited edition menu with dishes cooked to look like characters from the Gudetama series.

[35] In March 2016, Taiwanese brand Stayreal collaborated with Gudetama, and listed limited edition T-shirts, caps, cups, masks, and other products.
