Ice Climb

Ice Climb (サムサムアイスランド lit. Coldy Iceland in Japanese) is the fifth level in Crash Twinsanity and the first in the Iceberg Lab. At the end, there is a boss fight with Uka Uka. In this level Crash and Cortex work together as allies, for the second part.

Description
The first portion of the level involves Crash traversing through a hollow iceberg filled with machinery in a regular platforming segment. The second section features both Crash and Cortex exploring the exterior of the Iceberg Lab. Crash must throw Cortex to trigger switches and pass through the level. At the end of the level, Crash and Cortex fight Uka Uka as a boss after freeing him from some ice.

Water
Water is extremely common in this level. Falling into it will instantly make the player lose a life.

Height
Crash can die from falling from too high in most part of the level.

Hologram Probes
Floating camera like red robots that follow Crash's movements. These appear in Crash's section and the part when paired with Cortex. Being generic enemies they can be dealt with by any attack.

Bats
White-colored bats appear commonly throughout the level. When they see Crash, they will swoop down at him. They can be defeated with any attack, but it is interesting to note that when they are shot at by Cortex, the first one merely stuns them and makes them unable to fly, while the second shot kills them.

Icebergs
At the beginning of the level, there are several icebergs which serve as platforms. However, once you exit the cave with the icebergs and enter the inside of the mountain, the icebergs will sink slightly and will hurt Crash if he touches them.

Penguins
Penguins appear frequently throughout this level with rockets strapped to their backs. When they see Crash, they will either rocket straight toward him or shoot up into the air and attempt to divebomb him.

Fish
Penguin: "(angry squawking)"

Cortex: "The check bounced? Are you sure? Well, the past few years have kind of been slow. Wrath of Cortex didn't do as well as we'd hoped and-"

Penguin: "(loud angry squawk)"

Cortex: "...Fish?"

[Cortex extends his hand, offering a fish to the penguin.]

Penguin: "Grr..."

[The camera alternates between showing the angry penguin, Cortex's face, the fish, Crash and the penguins standing in the background. Suddenly, the fish in Cortex's hand is replaced with his ray gun.]

Penguin: "(alarmed squawk)"

[Cortex fires his gun, killing the penguin. The rest of the penguins rocket away in fear.]

Uka Uka boss intro
[Cortex flies through the ice, knocking Uka Uka to the ground and making a hole into the ice cavern. Crash jumps through the hole and lands on the ledge below. Uka Uka pulls himself out of the snow he'd gotten lodged in.]

Uka Uka: "Free... AGAIN!"

Cortex: "Mighty Uka Uka...!"

[Uka Uka looks down.]

Uka Uka: "Who has released me from my icy tomb?! My, my... Crash and Cortex? I don't know whether to kiss you, or KILL YOU!"

[Crash puckers his lips and makes kissy sounds, expecting the former.]

[Pieces of ice float upwards from the ground, forming a giant ice body for Uka Uka. Cortex makes a run for it, jumping down to the large metal platform below. Uka Uka makes a swipe at Crash, sending him flying down the platform, then jumps down there himself, beginning the boss.]

Uka Uka boss outro
[Uka Uka's ice body collapses. Uka Uka flies upwards and makes to leave.]

Uka Uka: "I SHALL RETUR-"

Aku Aku: "Uka Uka! Wait!"

[Uka Uka stops and turns back.]

Aku Aku: "An evil even greater than yours threatens to destroy this world."

Uka Uka: "NOOOO! ...That's my job!"

Aku Aku: "Seperated, we are but two magical masks. Join me, and together we will defeat this evil infestation."

Uka Uka: "I like a challenge... I accept!"

[The two masks swirl around each other and fly off.]

Aku Aku: "The Aku-Uka brothers, together again!"

Trivia

 * This is 1 of the 10 skippable levels in the game.
 * This level originally was going to have its own highly-energetic, rock n' roll musical score, but it was cut for being too unfitting.
 * Lava Caves, one of the cut levels in the game, would apparently have been the Tenth Dimension version of Ice Climb.
