r/FanTheories

Theory Briefing
- Hagrid is seen knitting something "the size of a circus tent" in yellow on the train to Diagon Alley — a detail Rowling never revisits.
- The blanket never appears in Hagrid's hut, which the fan theory argues rules out it being for himself or his boarhound Fang.
- Hagrid had just acquired Fluffy to guard the Philosopher's Stone, giving him a timely reason to knit something enormous.
- Hagrid's consistent habit of pampering dangerous creatures — from dragons to giant spiders — fits the idea of making Fluffy a comfort blanket.
