Caught a male Hoothoot, Named him Jack. Like Jack o Lattern because the eyes glow similar to one. I noticed that he was owning other Hoothoot, so I checked out his IV's:
HP : 30 - 31
Atk: 20 - 23
Def: 20 - 23
SAt: 14 - 27
SDf: 17 - 21
Spd: 29 - 31
--AVG: 22.0313 ... Sick for not even catching multiple Hoothoots
the IV system in Crystal is not based on 1-31, but 1-16. Check this page out for more info:
