The active player may collect a Lesson card from a doorway, if their Penguin has moved completely through the doorway.

If a player’s Penguin is partially in a doorway before the flick, then they cannot collect a Lesson card from that doorway after the flick. To collect a Lesson card from a doorway, a Penguin must begin its flick completely on one side and end its flick completely on the other side.

Moving a Penguin off a doorway with a Lesson card onto a free spot on a white line allows the Penguin to be flicked through that doorway and collect the card.
