This is a project to develop meta-animation and meta-games using ‘Dr. Egg’, a popular natural ecology and insect YouTuber with 500,000 YouTube subscribers, using the global metaverse platform The Sandbox. It is produced through a mixture of metagame content gameplay videos and traditional animation production methods, and has an adventure story about a boy who falls into the insect world and collects cards to return home. An animation and a metaverse game will be released simultaneously, allowing viewers to participate directly, and even utilize TCG-type cards by making use of the story of collecting insect cards.
