From the Super Mario Wiki

Wario walking around Treasure Square. The area behind him is Excitement Central.

Treasure Square is a not-so-big plaza in Wario World. This place has the game's five main areas branching off of it. Excitement Central, Spooktastic World, Thrillsville, Sparkle Land and the giant treasure chest where The Black Jewel sleeps. There isn't much to do here except save by hitting one of the books. There's rap music in the background.
