Be sure to do so with the use of a Pinap Berry. This will increase the amount of Candy gained after catching the Pokemon and assist with the other two objectives.Evolving Slowpoke into Slowbro requires 50 Slowpoke Candy. Evolving Slowpoke into Slowking will require 50 more Candy and a King's Rock item. King's Rock can be obtained through the event-exclusive research.
