Number 66, The Sea’s Legend, is a request that’s unlocked after you’ve captured a Qwilfish and evolved it into an Overquil. The reward for this request is pretty generous (three Comet Shards—which sell for P15,000 each) but the true reward is the location that you unlock during this request:Seaside Hollow, where Phione and Manaphy spawn.

Solving The Sea’s Legend’s riddle is pretty easy: just take yourOverquil, aMantyke, and aBuizelto thenorth of Sand’s Reachduring theevening. There’s an arc in that area where you need to pass through. You’ll know you did it correctly if you hear a Pokémon cry.
