I just had this guy pop on me in the same situation. I was camping the clicky and he popped instead of the young frog or warlord. He dropped two items for me:
Refined Grade A Choresine Sample Venom Saturated Earth
Had this guy pop for me on trap trigger, insted of A Young Frog or the warlord. Was hunting the clicky and very surprised to see this thing instead of the ph or named. Am 100% positive on this, killed many young frog PH before and after, in the same camp session. He dropped nothing.
