They are based on the CryptoRalph art and attributes which are uniquely combined with the Moonbirds traits. So basically this is the first time a Moonbirds derivative is based on a real person life (just like CryptoRalph).
BirdRalph holders will be able to collected CryptoRalph Token ($CRT) and level-up over time for additional benefits.
