Challenge #2 was to find a Pokemon and claim it. As long as you got at least one, you were good to go. But, now that Challenge #2 has ended, you can pick one of your Pokemon to evolve and one to make shiny. You can pick the same Pokemon to both evolve and make shiny (like what I did with my Raichu).

You can still search and claim Pokemon to add to your postbit, though. So if anyone wants to go back for whatever they didn't get earlier, the option is open.
