Birds of a Feather

Zack grooms his young student to take part in a karate tournament, against an angry ward of Bulk & Skull. The Rangers face the chicken-like Hatchasaurus monster. He's defeated quickly, but manages to regenerate using his inner sentient heart-creature, known as the Cardiatron. Jason, using both his Red Ranger powers, along with the Green Ranger powers, must face this odd being alone.
