After you complete all your training, you will be told to grab the wasp card from the map. Travel there, defeat the wasp queen and you receive her head as a trophy. Three villages return, simply equip the wasp head (up on the d-pad, items, trophies, wasp head, use) and press A. A count appears on the bottom of the screen and you must make sure all people (represented by the counter) see the trophy. Achievement unlocked and 30 renowned points.
