Dayo: Sa Mundo ng Elementalia (transl. Visitor: In the World of Elementalia or The Wanderer in the Land of Elementalia) also called Niko: The Journey to Magika in English-speaking countries, is a 2008 animated adventure-fantasy comedy film and the Philippines' first all-digital full-length animated feature film. Produced by Cutting Edge Productions, the film revolves around Bubuy who has to save his grandparents who were abducted and brought to the strange land called Elementalia, home to a host of strange creatures from Philippine mythology. This $1.3 million (roughly ₱58 million) production composed of over 500 local animators features a “tra-digital animation” technique using paperless 2D and 3D technologies. It has 2D animation for its characters and 3D animation for the backdrops.

The production team of Dayo spent several months developing the story, mood, and the whole package of the animation. While writing the script, the writers consulted a book on local mythology by Maximo Ramos entitled Creatures of Philippine Lower Mythology. Compared to the usual three-year completion of a traditional full-length animation, this film aimed to be finished within a short span of two years.

Dayo is written by Artemio Abad, Jr. and Eric Cabahug and directed by Robert Quilao. The film was released on December 25, 2008 as an official entry to 34th Metro Manila Film Festival.
