Hound

A  is one of the first monster types you'll encounter. It will attack the player on close range. They are very fast and can jump quite high, making escaping very difficult. They are not very resistant so any turret will be effective against them, and water can be used to slow them down.

Location
You can most commonly find Hounds near the surface or just below the surface, in the central portion of the world in the Grassy Hills biome.
