The Iceberg Lab is the Tenth Dimensional counterpart of Cortex's icy lair. It is only seen in Crash Twinsanity, where it is the first area in the Tenth Dimension. The large mountain in the center is now replaced by a large volcano. There is no snow covering the iceberg, and no lair present on the iceberg, but there are large fans and spherical energy domes, meaning that this possibly could have been the lab of Good Cortex. There would have been a Tenth Dimensional Capu Capu at the base of the iceberg lair that would take Crash back to the first dimension.
- There is a glitch where you can explore the ground level. You can walk on certain parts of the water and there is a trail of Wumpa Fruit leading down to where the boat would be in the normal Iceberg Lab.
- Despite this being the 10th dimension version of Cortex's lair, it still connects to N. Sanity Island's 10th dimension counterpart: Twinsanity Island. However, Cortex's Lair is much further away from N. Sanity Island.
