Morph was produced for the BBC by Aardman Animations, later famous for the "Sledgehammer" music video, Wallace and Gromit and Shaun the Sheep. Morph appears mainly in one-minute "shorts" interspersed throughout the Take Hart show. These are connected to the main show by having Hart deliver a line or two to Morph, who replies in gibberish but with meaningful gestures. Later on, Morph is joined by the cream-coloured Chas, who is much more troublesome and mischievous.

Morph can change shape. He becomes spheres in order to move around and extrudes into cylinders to pass to different levels of his environment. He can also mimic other objects or creatures. Morph lives in a wooden microscope box^{[citation needed]} on an artist's desk. He and Chas both love to eat cake, as seen in many of the shorts. Most appearances of Morph revolve around his friendship and rivalry with Chas, with each often playing tricks on the other and laughing at each other's misfortune. While Morph's nature is that of an innocent, curious character, Chas is much more mischievous and prone to bad behaviour.

After Hart's shows ended, Morph and Chas appeared in shorts on the Children's BBC's successor programme SMart from 1994-2005.

Some of the early plasticine models of Morph were destroyed in a fire at the warehouse where they were being stored on 10 October 2005.^[1]

Morph's 30th birthday was celebrated in 2007 by creator Peter Lord and celebrity fan and comedian Phill Jupitus at events for the Encounters Film Festival in Bristol. In March 2009, shortly after Hart's death, a flashmob of Morph characters was organised in London outside the Tate Modern art gallery.^[2]

In 2009, the BBC drama Ashes to Ashes featured Morph in a guest appearance as a representation of a present-day medic.^[3] Morph was used to give a comic feeling despite a very serious situation in episode 3 of the second series. The character was pictured in an episode of Take Hart; however, Morph appeared on the television after it was turned off, separating it from the context of the Take Hart episode.

On 29 October 2013, Peter Lord (co-founder of Aardman Animations), created a fundraising project on the crowdfunding site Kickstarter. The campaign set a target of £75,000 to be used to fund 12 new one-minute episodes. The target was reached on 6 November 2013 after only nine days, attracting contributions from over 1,700 backers, who received a variety of rewards, including early access to the new animations and a small box of clay used in the production, depending on the individual's level of funding.^[4][5] In January 2014, Peter Lord and Aardman began production on 15 new episodes featuring Morph. The new series premiered on Morph's official YouTube channel with 15 episodes from 4 July 2014 to 30 January 2015.

In 2015, a Morph experience opened at Land's End. The Land's End signpost was rebranded "Lamb's End" with original sets, models, and characters from a range of Aardman productions. Visitors were also able to star in a real Shaun the Sheep scene, using green-screen technology, and meet other characters from the Aardman family, including Shaun the Sheep and Wallace & Gromit.^[6]

Released between 20 March and 2 October 2015, HD-restored versions of The Amazing Adventures of Morph appeared on YouTube; and in the summer of 2015, Morph returned to TV on CBBC with the 15 new episodes.^[7] From 6 November 2015 to 7 January 2016, The Lost Tapes from 2001 were revealed having been redubbed and remastered on YouTube. In March 2016, it was announced that Sky had made a deal with Aardman Animations to produce new Morph material to be directed at its child audience.^[8] From 6 May 2016 to 15 September 2017, all clips captured from Take Hart were revealed on the Morph YouTube channel. In August 2017, new Morph merchandise was shown at Wallace & Gromit's Charity Shop.^[9] Between 2 March and 14 September 2018, 15 more episodes of the new Morph series that were previously shown on Sky Kids were shown on YouTube. From 15 February to 17 May 2019, all 13 episodes of The Morph Files that were remastered into HD were released on YouTube.

In May 2019, Morph and Chas appeared in an advert for Tesco as part of the company's centenary celebrations, which also featured celebrities Anneka Rice and Derrick Evans (the latter more commonly known as Mr. Motivator).^[10]

On 9 November 2020, the new Morph series, The Epic Adventures of Morph, appeared and began to stream on Sky Kids. The series features Morph, Chas, and two old characters—Delilah and GrandMorph—who were brought back to add more life to the show. There is also a very small cameo from Gillespie, who is another character from The Morph Files and The Amazing Adventures of Morph that was revived for the series.
