I actually just found a green shiny Spickle myself while training my Wariclaw and Worgeddon in Argite Cave :D I'm gonna train it and replace my normal Slagmite with it ^^ The best part is that the nature doesn't suck (neutral isn't good but it isn't bad either), and I could think of 15 bad natures for this thing. EDIT: Obtained Shiny Dribbik. EDIT #2: Obtained Shiny Slagmite.
