Clown

The Clown is a rare Hardmode enemy that appears during Blood Moons. The smiley bomb it throws will destroy nearby blocks when it goes off, like a normal Bomb; this makes Clowns a serious hazard to any structures. Its bombs can be shot out of the air with most weapons. Touching the clown itself may inflict the player with the Confused debuff.

Once you have defeated at least one Clown the Clothier will start selling the clown costume.

Tips

 * Clowns are the only enemies that actually put structures themselves in danger. Here are some tips to protect your work:
 * Replace your House's outer framework with Dungeon Bricks or raw Hardmode ores (Cobalt, Mythril, Adamantite), which are impervious to bombs.
 * Blocks that are impervious to explosions will not shield the blocks behind them though, so merely encasing your House with these will not provide much protection. A fair depth of a structure's outer framework will need to be replaced, or barricades made of impervious blocks can be constructed a fair distance away from vulnerable structures.
 * Build your house underground, or hide deep underground until the night is over, so that Clowns have no chance to spawn.
 * Travel several screens away from any structures you care to protect. Like all enemies, Clowns will only spawn near a character.
 * Build your house floating a fair distance above ground, or mine away enough blocks beneath and around your existing House (essentially making it floating), so that Clowns and their Bombs cannot reach it.
 * Put moats with Lava on either side of your base. Optionally you can install Active/Inactive stone drawbridges to make it easier for you to access your house. Note that Inactive Stone Blocks will still break from explosions.
 * With enough investment, a buffer of chests or storage items planted on tiles will offer complete protection against all explosives. See Storage Items.
 * The Clowns bomb have a 3x3 blast radius meaning a bomb proof wall must be 3 or more blocks thick.

Trivia

 * The Clown may be a reference to the Mario games' Lemmy Koopa, a similarly multicolored enemy who also balances on a ball and throws bombs.
 * Or it may be a reference to the jesters in the Kirby games. The jester throws bombs and sometimes balances on apples.
 * During a Blood Moon, the Demolitionist may mention that his bomb went missing; it is possible Clowns take the Demolitionist's bombs and wield them.
