Walrus Camp

Walrus Camps (or Igloos) are naturally generated structures that spawn the following hostile mobs: MacTusk, Wee MacTusk and Blue Hounds. They are used as a base by these mobs, known collectively as the MacTusk 'n' Son Scottish Nobleman Walrus Hunting Party. The Walrus Camp will only spawn mobs during Winter. Walrus Camps will spawn on all terrain, except Marsh Biomes. Often two or more camps will spawn in a close vicinity to each other. The MacTusk Hunting Party will spawn every 2-5 days from a fully functioning Walrus Camp.

Side Note: If you're standing by the Igloo as Winter sets in, it won't become a camp until you go off screen.

Appearance
As its nickname suggests, the Walrus Camp is an Igloo, with a wooden door, with a window and a chimney. During the Summer, the Walrus Camp comprises a ring in the ground, coloured black, with purple streaks.

The Walrus Camp will not light up at night if all members of MacTusk 'n' Son Hunting Party are dead. At night time, the Party will not spawn.

Note: in later versions, 2 Blue Hounds will guard Walrus Camps at all times and will cause MacTusk 'n' Son Hunting Party to appear if player is too close.

Strategy
Since Walrus Camps are spawning enemies ( Blue Hounds and Walrus hunting duo) you can try to trap them or kill them as they spawn. One of the easiest ways to do that is to place a couple of Spider Dens using the Spider Eggs during summer in order to let them grow to at least Tier 2. During winter, the camp will continuously spawn Blue Hounds and they will automatically trigger aggression of the spiders, dying in the process as spiders will simply overwhelm them. The camp will spawn hounds indefinitely, making it a perfect farming ground for items such as Hound's Tooth, Blue Gem, Walrus Tusks and other speciality items. To further simplify the farming for yourself you may want to bring Spiderhat to render spiders in vicinity non-hostile.

Tips

 * Planting Spider Eggs outside Walrus Camps at the beginning of Summer is a good way to farm Tam O'Shanters, Tusks, Teeth and Gems.
 * Bases near Walrus Camps are ill-advised.
 * Should you wish to fight the Walrus Hunting Party, Boomerangs and a Tentacle Spike, Dark Sword, Bat Bat etc. are recommended.
 * Use a ranged weapon (Boomerang, Blow Dart, Sleep Dart, Fire Dart, etc) to kill MacTusk and WeeTusk, and a melee weapon to kill the Hounds.
