How to get
Originally planned to be at the grand prize for the October 2016 TradeFest, the TradeFest was cancelled and the panther was made available for 20 Ghost Doubloon (instead of 30) at Ghost Ship Cove trade panel slot 3 (instead of the Eternal Ghost Chest during November).
Reward for the October 2016 TradeFest (eventually cancelled) with a new Gnome Leaf Blower decoration.
