ShibaTama

During the Meiji Restoration, western puppy breeds were imported, they became so popular that almost no pure Shiba remained. To save Shiba Inus, Inugami, the god of dogs cast a spell to give 3,999 new born pure Shibas the ability to dress like their owners, allowing the puppies to grow with them as very close friends. These puppies are the Shiba Tamas. All Shiba Tamas blended in perfectly until hunters from around the world came to catch’em all, and trapped them inside the Ethereum Blockchain. The Shiba Tama House is now sending a distress signal to everyone of you to come save Shiba Tama. Join our community and rescue these cutes Shibas!
