Iceberg Lab

The Iceberg Lab is one of Cortex's bases which It appeared in Crash Twinsanity. Even though it was never seen being destroyed, Cortex had created a new base in Crash of the Titans. The bottom of the lab has a few reachable islands with gems to collect and hidden creates. After you defeat Uka Uka, you are able to go into another room, where you and Cortex fight some of the ants the Evil Twins send. After defeating all the ants, you go into another room where the "improved" Evolvo-Ray, the Psycotron, can teleport you to the Tenth Dimension. The Psycotron is actually a failed version of the Evolvo-ray, this can be proved by watching Cortex's childhood movie, where he tests the Evolvo-Ray prototype on his parrots Victor and Moritz.

Cortex's air ship is attached to the Iceberg Lab, it can take you to Madame Amberly's Academy of Evil.

Also on the second floor (throne room) you can use the Psycotron that takes you to Victor and Moritz's stronghold of evil, Ant Agony.

There is also a lift that can take you to Slip Slide Icecapades and Rockslide Rumble.

After it fell out of disuse it began to melt (it can be seen melting in the background of Mystery Island in Crash Tag Team Racing) and the structures likly sunk by now.
