Snowboarding

Snowboarding was a level mode used in Secret Agent Clank for races and quick-escapes. It could only be used for certain levels, and is the exact same as boat rides.

Difficulty
The difficulty of these levels is commonly said to be difficult or impossible. These levels are for some reason easy on your second try.

Trivia

 * Snowboarding is probably based off of games with quick snowboarding escapes like Sonic Adventure.
