Olyfactory is a bit of an odd company. They didn't have a legal license to create Pokemon plush, so all Olyfactory plush are technically bootlegs. However, they made their own patterns rather than just copying the design of already-made plush, so there a lot of unique and sought-after plush created by Olyfactory! Pokemon finally cracked down on them and they are now out of business, so I expect the brand will increase in rarity over the years.
