The rarest of Rappies Help!!

How can i complete this quest?? Where can i find him?? Pls help o/

I think this requires the Emperappy, which is an extremely rare spawn that can happen in any quest/mission's area.

"Rarest of Rappies" is just the normal rare Rappy, or currently Frog Rappy, not Emperappy.

Rappies are a rare enemy spawn that can occur in pretty much every quest, but you will probably have your easiest time finding them in an Advanced Quest since those can get a rare enemy appearance boost.

Thanks guys i really appreciate!!
