You firt go to the ntional park, in the gap in the fence, turn right. here are trees. one tree has a slightly wider spacing. (the second row of trees up from the building), walk into that row of trees. you can walk on thm. go right into the trees. (make sure you have strong pokemon with you! at least lvl 12, 13 14 or over.) battle the little girl. she has a chansey, and a real cute delcatty, both level 25 or 20, i cn't remember. well- battle her , (oh! leave an empty socet in your pokemon, so that treeko can be taken) after battleing she gives you a treeco that is level one. it is easy to train up! When a park competition comes (bug cathching contest!) enter the park, cath a strong bug at least lvl 15. then claim prize, enter park 'ARD' will battle you, go back to gap in tree claim another treeko! she dosen't battle you twice!
