Grammarithmos

You may know that in the shows, Alphaland and Numberland are depicted as two separate planets, but here, it's actually one big planet known as Grammarithmos (coming from two words from Greek that means letter and number respectively). It is as big as Earth, but rather a bit smaller, as well as a bit less mass, and is the fourth planet of the Fragmosa system. It has one moon orbiting around it named Calculata. Grammarithmos has two major continents; Alphaland and Numberland. Shown below is the geographical map of Grammarithmos 

In Grammarithmos, there are two sophont species of zontouvlaki, each ruling over a single continent; The Alphablocks of Alphaland and the Numberblocks of Numberland. They, along with their relatives of each continent are classified together in a new class named Alithotouvlaki ('true blocks'), alongside wingplanes, monkeyblocks and cubecanines. Shown here is the further classification.
