Cell edits are also used to allow some icebergs, ice chunks and rowboats floating in the water to animate and gently bob around. Without cell edits to modify specific references, the references that are on land would also bob. Bobbing icebergs will occasionally emit a cracking sound effect. Bobbing ice chunks will gurgle. An optional file for longboats is provided but static objects such as crates and barrels will not move with the boat.
