This spring, visitors to South Korea's Lotte World theme park will find a whole new world to discover as Underland makes its public debut.

Located in a space underneath the main theme park formerly occupied by a public mall, Underland is an all-new themed entertainment zone.

Guests to the park will be immersed within this colourful new world, home to friendly ogres inspired by the popular Korean fairy tale entitled 'Ogre's Magic Club'.

"For over a decade now there's been talk of turning the mall space into additional theme park area, but with the spike in attendance over the last year, the idea was put on the front burner," said Taylor Jeffs, director of design for Hollywood, US-based design firm and project creator, the Goddard Group.

Featuring an interactive XD Theatre created by Triotech, along with four new food and beverage locations, phase one of Underland increases Lotte World's guest area by over 22,000sq.ft.

In addition, the fun and lovable ogres who will inhabit the land, created by famed character designer and long-time Goddard Group collaborator Phil Mendez, will significantly expand Lotte World's overall family of mascot characters.
