Breeder Rank: B
Monster Rank: Any (Strong monster recommended!)
Location: Farm (every Month 8, starting in year 1005)

Once you hit the year 1005, your tree in the southeast corner of the farm area will be fully grown. If you bring your monster there in Month 8, you fill find an event crystal. (This is the same as Beaclon in MFDS1.) Cleo will mistake the monster on the tree for a a Beaclon, but it is really a Hengar. The Hengar will attack. If you defeat it, you will get the Ancient Weapon (a Hengar Doll...) and Hengar will be unlocked.
