2 things:

1: These can spawn in super shallow water in crystal isles, beware

And 2: A fun challenge would be to get a large group of friends, build sail ships on some rafts, arm them with ballista sand cannons, man each raft with at least 3-5 men each, name 1 person the captain, he orders everyone around, and try to hunt down the white whale (Alpha Leed)

It’s kind of a role play thing, but trust me, it’s so fun! Does require a hefty amount of people though.
