Gnarled Forest Survival was a minigame located in Gnarled Forest. To play, players had to use quickbuild to build an Idol Model for Reene Tombcrusher. To unlock the quickbuild, players had to use a Rank 3 Thinking Hat Showcase. Stromling Pirates, Admirals, and Apes spawned rapidly during the mini-game. This minigame was scrapped after Alpha testing, and it is unknown whether it would have appeared later if LEGO Universe had not been closing.
- Up until the middle of Beta, the achievement for building Reene's Idol could be found in the Gnarled Forest section of the passport.
- Gnarled Forest Survival never made it into Beta, only to be seen in Alpha.
