Migalus

Thank you so much

Hi everyone, apologize for my poor english, just started the game few hours ago, and i stick to a beginner guide btw =) Got my Nidorina F at 163 happiness, first badge, Headbutt learned, and after i've tried every tree (with the sleep face) i got this message "nothing happened". Is there something i did wrong ? (i really try to interact with possibly 20 trees from the beginner zone , and allways the same message "nothing happened")
