Special Rules Before the Collect Light step of the End of Season procedure, all Small Pines that are in the shadow of something else must be replaced with Big Pine treeples.Note: Only Small Pines that were in shadow before the Collect Light step grow up into Big Pines, not those that would become overshadowed only after a new Big Pine is placed during this step.
