I've been trying for literally 12 hours to get ANY sort of mutation on a heibok.. I use the octro plushie and the clover blossom so I can grow faster, all I have got it's nothing, health or stamina, Not a single GT/Shadow/Albinism/Double red, and so on.. so NOTHING.
It's very difficult to me to do the nesting method and upgrade the nest, since It's going to take so much time for me to do that alone and I have some issues w my wifi so, yeah..
