Okay so today (Sept 20 2017) CoD was the Chameleon Fish. According to the Wiki he has one location on Krotopia to be caught. Having never caught one personally, I figured this would be a great opportunity to both add one to my collection and gain a bit of coin. But I spent all my activity points catching the fish that existed in that area and never once did I see any Frost indicators. Has anyone else encountered similar issues in the past?
Darn! I've had this happen to me too. It's most likely just very bad luck. Hopefully you can try again for one another day and actually get it whilst you still have energy left ^^ Good luck!
Chameleon fish is also found at Nomad's Camp and Serpentine Escape. Go to castle tours and look for those houses. I have caught several at the Nomad's Camp. Good luck and have fun.
