Deckstar is the third level of the episode Turtle Soup from Jazz Jackrabbit.
Deckstar is another straightforward area of narrow pathways and no hazards other than a few moving springboards which may bounce you back. The tough Elite Doofus Guards are everywhere patrolling the platforms though, so be careful when navigating. Right after the checkpoint on the first area you'll come into a zigzagging high-speed section. The second area is a large vertical climb which culminates into another high-speed section, this time a simple left to right corridor.
