In 2021, in the lead-up to his wedding to Mrs Doodle, Mr Doodle made nine sets of prints of hearts in nine colours. The artist has also made colourful parodies of other famous artworks, including The Garden of Doodley Delights (2019) after Hieronymus Bosch, Mr Doodle Screaming (2019) after Edvard Munch, and the Mona Doodle (2019) after Leonardo da Vinci.

Recreations of images of Donald Trump, the Queen, Kim Jong Un, the Eiffel Tower, Tower Bridge, and Vincent van Gogh's The Starry Night (1889) were made with complex arrangements of Mr Doodle's signature characters. In the 2018 solo show Doodle World at Seoul's ARA Art Center, the artist showcased new works that adapt imagery of iconic landmarks, people, and artworks. Playing to the weirdness and performative antics that make the artist's alter ego come to life, Mr Doodle's clothing, worn at the completed exhibition, was hand-decorated to blend in with the doodle-saturated rooms of the installation. The simple imagery itself has broad appeal, with the artist stating: 'My intention has always been to create a universal doodle language that can relate to and attract people from all over the world.' Mr Doodle has referred to his style, which packs overwhelming visual stimuli into infinite compositions, as 'graffiti spaghetti'. He also drew over a grand dining set and accompanying tableware with floral centre piece.

Drawing influence from everyday phenomena such as cartoons, cereal boxes, and video games, as well as a retinue of imagined characters from Doodleland, the artist decorated walls, columns, and the floor of the gallery with dense imagery.

In 2016, Mr Doodle's first major solo exhibition, Attention Seeker, saw London's Hoxton Gallery covered in a continuous doodle mural.
