S1E17 Native Son

As Tygra and Lion-O navigate the snowy mountains in search of a safe route, they stumble upon a hidden village of tigers. To Tygra's surprise, he discovers his biological father living there. His father reveals the heartbreaking reason for sending Tygra away as an infant: it was to protect him. However, the village harbors dark secrets; the tigers are under a curse, and Tygra might hold the key to their salvation—though it could come at the ultimate sacrifice of his own life.
