An old Zoroark with a new move
If you love free Pokémon events and are located in the US, you’ll want to whip our your 3DS now and get to downloading. For owners of the Rubyand Sapphireremakes (dammit, why can’t they all be for X & Ytoo, where my full collection is), you can boot up your copy and choose the Internet mystery gift option to net “Sludge Bomb Zoroark.”
This particular Pokémon is level 50, has the illusion ability, and comes complete with Sludge Bomb, which it can’t normally learn. Nintendo hasn’t given a set date for the end of this event, so get to it when you can.
