The Stalking Sea Snake is a boss in Contra: Legacy of War.
Description[]
The Stalking Sea Snake is encountered while riding a raft in the river. It goes above and below the water and circles around, occasionally dropping green Blobs on the raft. There are also Ledders around the area the raft goes through that snipe at the player. The raft eventually comes to a stop by a concrete structure and the player fights the sea snake there.
