Boris Johnson meeting primary school pupils

The video tutorial begins with a brief mention of Star Wars, followed by a discussion on task completion. It then explains the concept of home credit, identified as a red word, and introduces the idea of blocks and a special friend. Finally, the video introduces a letter, wrapping up the tutorial.

What might 'Special friend' refer to in a personal context?
