According to Sohu Video Network, the human body of a happy hero refers to Jian Wu, the real character of Tellega Altman. This terrier is called human body because Jian Wu can be transformed into Triga Altman in Triga Altman animation, and the happy hero is nicknamed "Happy Hero" by netizens, because the pet phrase of this character is transliterated as "smiley Road", just like English Smile.
