If a player’s Penguin is close to a wall (doorways count as a part of a wall) or is stuck in a doorway, before a flick the player may place it on the closest spot on the white line free of other Penguins, even if it is covered by a card.
When doing this, make sure that the center of the Penguin is on the white line.
If the white lines in the corners of the boxes are covered with Exam cards, the line is considered to be present under those cards, and can be used to place your figure on.
