Twee uur durende remake van de originele eerste aflevering, ter ere van de anime die 20 jaar wordt uitgezonden. De special vertelt wat er gebeurde op de dag dat Shinichi werd getransformeerd in het lichaam van een kind. De special bevat nieuwe scènes die niet in de originele manga of de eerste anime-aflevering voorkwamen.
Nee, helaas is 名探偵コナン エピソード"ONE" 小さくなった名探偵 nog niet beschikbaar op Netflix in Nederland.
