Jammbo

Jammbo is the planet which serves as the setting for Jelly Jamm. This fantastical exoplanet is regarded in canon as the source of all music in the universe. Music is distributed from Jammbo to every other corner of the universe via the bubbles which are released from the Music Factory and into space.

Geography
Judging by the lyrics and music video of "Jump!", as well as the fact that the Sun appears to set and rise much like on Earth, Jammbo orbits around a sun - whether this is the same Sun in our Solar System or another star serving as the Jammbonian sun is unconfirmed. The length of a day, month or year on Jammbo is also not confirmed, but the appearance of calendars in episodes such as "Goomo's Birthday" implies that time is divided into days, months containing 31 days, and weeks on Jammbo.

According to the official Jelly Jamm Tumblr blog, Jammbo can best be described as a "whole planet inside another planet, the exterior cover acting as some kind of nutshell that protected the core where the kids, King, Queen and Dodos lived." The exterior cover of Jammbo gives portions of the core differently-colored appearances, and is filled with holes which allow for the musical bubbles to flow out of the planet and into space, to eventually end up in other places and produce music.

The surface of the core of Jammbo bears a close resemblance to the Earth, with a sky, what appears to be grass, and a variety of different plants. The landscape is mostly flat, but with numerous hills and mountains that typically take on rounded rectangular forms. Saltwater (Mina mentions sea salt in "Mamma Mina") and freshwater in the forms of lakes, ponds and puddles are both known to also exist on Jammbo, adding to the surface's ability to sustain life. Judging by the fact that digging underground is also possible, it is implied that Jammbo's surface has underlying layers much like Earth.

Jelly flows through the center of the planet, and houses the musical energy that powers Jammbo. On Jammbo, music must be playing on the planet or else life will come to a standstill - quite literally, as shown in the events of "The Jelly Must Flow!". Therefore, music can be heard wherever one is physically located on Jammbo.

Climate
Jammbo has a relatively mild climate with occasional precipitation, bearing a resemblance to temporal climates on Earth. Official artwork on the Jelly Jamm Facebook page depicted the characters playing in the snow and wearing winter outfits, which implies that Jammbo's temperatures can drop to low enough for snow to form.



Jammbo has seasons much like Earth, judging by the fact that there is a Spring Festival being held in "Soundcatchers".

Flora
Jammbonian flora usually manifests itself into the form of plants which make sounds. Such plants are typically found in the forms of flowers and trees, with some notable examples being La-La Plants, Burst-Into-Song Flowers, and Oofaloo Trees. Often, these plants resemble musical instruments found on Earth, such as cymbals, chimes or drums.

Fruits and vegetables are also known to grow in Jammbonian soil. Jelly Berries, Whistlenuts, Jelly Apples, and musical mushrooms are among some of these edible crops. Jammbonian soil can also sustain crops resembling those on Earth, judging by the prominent appearance of a musical plant resembling and referred to as "bamboo" in "Queen's Birthday" and blackberries in "Princess Smile". Rock-like formations, including one with what appears to be a frowning face on its side, have also been observed on Jammbo.

Fauna
Two varieties of living creatures dominate the population of Jammbo. The human-like, intelligent life-form is known as the Jammbonian alien, but the population of Jammbonians is outnumbered by that of the animalistic Dodos. According to Bello and Goomo in "Jammbo's Many Worlds", octopi and jellyfish also are known to exist in Jammbonian waters.

Culture
There appears to be much Earth influence on the culture of Jammbo, judging by its architecture and the lifestyles of the Jammbonians. They even speak and write fluently in English (with English as their spoken language being replaced with whatever language the dub is in for foreign dubs). Jammbonians have also adopted advanced technology like video games, television, and smart devices.

Jammbonian cuisine also includes a variety of Earth foods, such as cakes, watermelons, bananas, turkeys, vegetables like celery (first shown in "Mina's Party"), pies, and even mint chocolate cookies (in "Queen Rita", Rita mentions them).

Jammbonians do not appear to celebrate Earth holidays, but they do host seasonal festivals (at least a Spring Festival) and music festivals. The Halloween special, "The Monster of Boredom", does not take place on Halloween proper and the costumes are only used for role-playing the story of the monster. There is official artwork of the characters dressed in Christmas attire, but whether or not the characters really do observe Christmas or even practice any religion is not confirmed.

Government
Monarchy is the main form of government on Jammbo. A King and Queen rule over the entire planet.

Etymology
There has never been an official confirmation as to why the name of the planet Jammbo was chosen and its significance. It may have been derived from the word "jamboree", fitting with the fact that music always plays on the planet and its residents love to have fun.

The name "Jammbo" also resembles "jambo", a Swahili word for "hello". However, it is not likely that the name of Jammbo was derived from this, though this connection may have played a part in the reason why Jelly Jamm of all series got a Swahili dub, a rarity in the dubbing world, in 2020.
