In Nimbus Park, a troll carrying around LEGO bricks could be seen as a background character, but played no role otherwise. Another Troll wielding a large club played a bigger role in the first known version of Youreeka, located in a hedge maze. The Troll here would have offered a mission to collect him some water. Due to Nimbus Park and Youreeka being merged into Nimbus Station, the Trolls were removed, and were not officially released in the live game.
Trolls were also set to appear in Spikes Peak, a mining themed world with trolls and dwarfs.
Several trolls appear in concept art of various siege wagons for the Kingdoms World, suggesting that they were intended to make an appearance in the unreleased world as operators of these battle vehicles.
Like Burno, the Troll is modeled after the Giant Trolls of the Castle line, such as the Giant Troll included in the 7038 Troll Assault Wagon set.
On December 19, 2011, a LEGO Universe GM named Shival hosted a party for players in Nexus Tower, spawning various NPCs and creatures, including the Troll. On January 30, 2012, the Troll reappeared in another Mythran-hosted party held in Nimbus Station.
