The Derp Birds NFT project is a collection of 10,000 Cardano based, unique NFT collectibles, which have been beautifully hand drawn.
There are 14 different Archetypes in total with different traits and attributes to distinguish them from each other and they all live in the land of Dertopia
When a Derp Bird, manages to master its archetype and has been rolled with the same archetype in every attribute slot it becomes a perfect specimen and are the rarest of the Derp Birds collections and these come with a special background layer associated with their archetype.
The colour of your Derp Bird comes in all the colours of the rainbow plus more, which also impacts the rarity.
