As a result of the Tamagottsun, many new locations and mysterious side-effects occur in the town, especially in the school.
The name comes from dorimu, the Japanese pronounciation of the English word dream, and Tama, which is short for Tamagotchi.
For the first time in 1,000 years, Tamagotchi Planet is perfectly aligned with Earth. The two continents of Tamagotchi Town and Dream Town join together to celebrate with each other, thus combining the towns and forming DoriTama Town. This phenomenon is known is "Tamagottsun" (たまごっつん), which is Tamagotchi combined with the Japanese verb gotsun, meaning "thud" or "bang".
