During an "ABC News" interview, president of Creatures Inc. Tsunekazu Ishihara gave insight into the brainstorming process for developing new Pokémon species. He explained, "The ideas for each of these monsters came from the imagination of the software developers at Game Freak who get these ideas from their childhood experiences, including from reading manga, the name for Japanese comic books. Ideas come from scary experiences they had as kids, catching insects, and so forth. So from these experiences in childhood, these ideas for Pokémon came out". In the same vein as the Pokémon Mew of "Red" and "Blue", the exclusive Pokémon Celebi was included in the "Gold" and "Silver" games but is only accessible after attending a Nintendo promotional event. The first official event offering Celebi was Nintendo Space World 2000 in Japan, in which 100,000 attendees would be awarded the rare Pokémon. In order to be selected, players had to send in a postcard to enter a lottery for one of 100,000 certificates of Celebi, allowing them to enter the event and obtain it.
