Defeat Obalis in a pet battle.
I see the triumphant tamer returns to again test himself against me. Very well. I accept your challenge.
You will also receive:
Pyth (Beast)Spring (Flying)Clatter (Critter)
Beat him very soundly with Dragon Kite, Celestial Dragon and a Flayer Youngling. Could probably duo with the latter two and fill in a leveling pet for the third spot.
