11. Seeker of Hi5 to MapleSEA Treasure Hunt Event (26th May ~ 14th July 2010)
Talk to NPC Joyce and she will teleport you to the treasure hunt map. Inside the map, you will not be able to use skill such as teleport or flash jump. Boxes with random rewards will appear at random location within the event map. You will need to search for a Hi 5 Treasure Map by destroying boxes with your normal attacks. This Hi 5 Treasure Map will allows you to exchange for a special gift with NPC Vikan. A special 5th Anniversary chair is awaiting for you as 1 of the many gifts at NPC Vikan.

this event rox. even though it's very hard to find the treasure map, the boxes drops 15% scrolls. and it drop pretty often too. i got like 8 earring int scroll and 5 glove atk scroll.
and the boxes drop minigame items like omok (the completed one where you can use it to play minigame), power elixer and some other stuff.
