In 2020, Shiba Inu was gifted to mankind by Ryoshi

Shiba Inu exceeded all expectations, but something was lacking

An heir to carry on its esteemed legacy 

Hence, the birth of Baby Shiba Inu in 2023

The one and only ideal homage to Shib

And the arch-rival of Baby Doge 

Following the path paved by Ryoshi

It was fate

Both Shiba Inu and Baby Shiba Inu

Will rule the memecoin world

United in ascent

Byoshi.
