Rusty Walrus

Rusty Walrus is a genetically enhanced walrus who appears only in Crash Twinsanity, and later Crash Bandicoot Demensial Sanity. He works for Doctor N. Gin as his battleship's cook. He is best known to be a major threat to both Crash Bandicoot and Reese.

Twin Crisis
Not much is known about Rusty. What is known is that he is a chef under the employ of Dr. N. Gin (as depicted from his apron).

After both Crash and Reese defeat N-Gin, the duo fall from the rows nest and crash into a narrow corridor where Rusty then appears from another room. He sees Crash and Reese on the ground and says, "Ah yummy, fresh meat and Sushi for my pot!", to which Reese would state through a nervous look saying "I think you might be confusing us for something else" Rusty starts chasing after Reese and Crash.

The chase that ensues is much like the traditional boulder dash levels of previous games. Obstacles include holes in the floor (which strangely Rusty walks over some of them), Nitro Crates (which Rusty is surprisingly immune to) and burning-hot steam. After the chase, Crash and Reese escapes.

It is unknown what became of him after N. Gin accidentally set off the major TNT explosion, but since he was immune to the nitro crates, he was probably immune to the TNT's explosion.
