Furby 1998: Generation 1 was first released in October of 1998. These were the first Furbys to ever release worldwide. These are also the most common furbys due to how many were purchased and produced. This generation is based on animals, and is the only generation of furby to not come programmed with Deep-Sleep Mode. Noteable furbys include Skunk (For the amount of demand by fans) and Leopard (For being the most common furby in the world).
