Terraria – King slime biome requirement

According to the wiki there are three types of functional statue:

1. Statues that spawn items
   • Bomb statue - spawns bombs
   • Heart statue - spawns hearts
   • Star statue - spawns mana stars
2. Statues that spawn enemies
   • Bat statue -spawns a bat
   • Bird statue - spawns a bird
   • Bunny statue - spawns a delicious dinner (or a murderous beast during a bloodmoon)
   • Chest statue - spawns a mimic
   • Crab statue - spawns a crab
   • Fish statue - spawns a goldfish (corrupted during a bloodmoon)
   • Jellyfish statue - spawns a jellyfish
   • Piranha - spawns a piranha
   • Skeleton - spawns a skeleton
   • Slime - spawns a slime
3. Statues that teleport NPCs
   • King statue - teleports a random male NPC to the statue
   • Queen statue - teleports a random female NPC to the statue
4. Bonus: Dart trap - fires a dart which damages and has a chance to poison the creature hit

The item spawning statues can spawn an item approximately every ten seconds.

There is a limit of three spawned monsters of a given type that can exist in the world at one time. The monsters spawned from statues do not drop money, but, with exception of the mimic, do drop items. During a bloodmoon bunnies and goldfish will immediately turn corrupt and will drop money when killed. Because the corrupt versions do not count towards the 3 spawn limit, they can be spawned and harvested for cash quickly.

Any statues not listed do not have a known function.

Pretty much all of the biomes (using Terraria's liberal definition of "biome") can be moved to another location, within certain limits.

The most extreme example is a Meteor crash site biome, which can exist anywhere, at any height. At the other end of the spectrum, we have the Dungeon, which cannot be moved at all.

Completely immovable

• The Dungeon, because it requires an unsafe background wall below the Dirt Wall depth (cannot be placed by the player).
• The Underworld, which is restricted to the very bottom of the map
• The Sky, which, like the Underworld, is just there at a certain altitude.

Mostly immovable

• The Ocean is not completely immovable, but very inflexible. It is both restricted to a certain height (above the surface level), and can only exist within 250 blocks from either edge of the map. You can create an artificial Ocean in the middle of the map, but that won't spawn Sharks, nor will it grow Corals. Creating artificial Oceans that sort of float above the real one does work; I have actually done so to farm Corals.
