Slangcity is the capital of the Kingdom of Berko. It is the first city in Berko. The leader of Berko, Mister_Moinz, plans to make Slangcity bigger and safer.

Slangcity has a shrine to Grootslang where the dragon egg is located after Dieter_Ness and Mister_Moinz slew the dragon on 2021-08-25, just 5 days after the beginning of the world on 2021-08-20. It also has the Snakes Tongue Adventure Guild which functions as an inn at the same time.

Slangcity has been erroneously, but frequently, referred to as Slangtown, a mistake initially made by PatAPizza56 on 2021-08-31.
