Multiple spin-offs were created, including stage productions and LazyTown Extra, a short-form series for younger children.

The series follows Stephanie, a pink shy but sassy 8-year-old[7] girl who moves to LazyTown to live with her uncle, Mayor Meanswell, and is surprised to learn that its residents lead inactive lifestyles.

They are opposed by Robbie Rotten, who prefers to lead a sluggish life and devises schemes to make LazyTown lazy.

Ziggy has an unbalanced diet devoid of fruits and vegetables, Pixel is reclusive and spends too much time on his computer, Stingy is self-centered and possessive, and Trixie is a troublemaker with little respect for rules and other people.

[8] Each episode features at least one original song and concludes with a performance of "Bing Bang (Time to Dance)", sung by Stephanie.

A second stage show based on the third book titled Glanni Glæpur í Latabæ (Robbie Rotten in LazyTown) debuted in 1999.

Nickelodeon Australia reported that by the time the second play finished touring, LazyTown had become a household name in Iceland.

[14] A variety of tie-in products and media were created in the country before Scheving decided to develop LazyTown into a television program; these included bottled water, toy figures, and a radio station.

According to Le Gué, "We start with the live actors and puppets on a physical set with a green screen behind them as a backdrop.

[36] The Spanish-dubbed version also airs on Telemundo (a sister station to NBC) as part of the weekend pre-school morning block MiTelemundo.

In Brazil, the two first seasons of the show was broadcast with Brazilian Portuguese dubbing on SBT (on the children's television block Bom Dia & Cia), and subsequently on Discovery Kids and Cartoon Network.

[38] The Hollywood Reporter's Marilyn Moss praised the show's intentions to encourage exercise, calling it "great fun for the very young set, not to mention educational, maybe even life-changing.

"[39] Justin New of The Washington Times called LazyTown "a great show" and stated that he admired the Sportacus character.

[41] Pete Vonder Haar of the Houston Press called LazyTown "pretty much the creepiest show on TV since Twin Peaks", citing the "off-putting" mix of live-action and puppetry.

In 2005, The Boston Globe stated that the program "has sparked a cult of healthy living among a certain preschool set [and] has a grown-up following, too.

"[43] Lynne Heffley of the Los Angeles Times stated that LazyTown "has zany appeal, even to viewers who are no longer 'junior.

'"[44] In 2008, the song "Cooking By The Book" from the sixth episode "Swiped Sweets" went viral when it was remixed with Lil Jon's part from his 2004 Snoop Dogg collaboration "Step Yo Game Up".

A GoFundMe page was established by LazyTown head writer Mark Valenti to help the actor as he endured his illness.

[55][56] To thank his supporters, Stefánsson celebrated by uploading a video of that song performed with his former cast members and LazyTown's composer.

[59] On 15 September 2008, a spin-off television series called LazyTown Extra debuted in the United Kingdom on CBeebies.

Fisher-Price partnered with Viacom's consumer product division to produce the merchandise, all of which was designed to encourage physical activity.

[37] From June to August 2005, LazyTown's Stephanie hosted the "Nick Jr. Power Play Summer" event, which involved a series of television spots that replaced the channel's standard on-air continuity.

Similarly to the live performances and the program itself, this campaign was an experiment designed by the network to increase awareness of exercise and nutrition in its preschool audience.

[70] New productions of LazyTown Live had their premieres in November 2009 in Portugal and in March 2010 in Spain by producers Warner Bros. Entertainment.

A stage play premiering in 2011 introduced the character and concept for Roboticus, which became the first episode of Season 3 of the show in an abridged form.
