Editing House of Boom

'''House of Boom''' ({{ja|トラップルーム|Torappu Rūmu}}, ''Trap Room'') is [[Steve]]'s [[Final Smash]].

Steve places an oversized piston block in front of himself, which then extends outwards to hit any opponents in range. The first victim caught is taken into a cutscene where they are thrown into the House of Boom, a structure filled with TNT and mobs. [[Creeper]]s and [[Zombie]]s attack the victim, producing an explosion. Steve enters the frame and eats a "victory steak", after which the victim is launched. Any other opponents struck by the Piston will take knockback from it. Steve also crouches three times and looks toward the camera upon completion of the Final Smash, akin to his [[down taunt]].

In ''Minecraft'', pistons are crafted with three wooden planks, four cobblestone blocks, one iron ingot, and one redstone dust. They can push other blocks, mobs, and players around when given a pulse through a redstone circuit, although whatever they push only travels 1 block away rather than the launching that is seen in ''Super Smash Bros.'' The giant piston seen in ''Super Smash Bros. Ultimate'' does not appear in ''Minecraft'' and exists only as part of Steve's final smash.

While the House of Boom does not naturally generate in ''Minecraft'' worlds, it bears a strong resemblance to both strongholds and jungle temples, structures that naturally generate in the Overworld. The former serve as the only entrances to the End dimension, where the fight against the Ender Dragon takes place (although unlike the House of Boom, strongholds are found underground rather than on the surface) and the latter contain chests guarded by traps. There are other structures in ''Minecraft'' that contain harmful traps, such as desert pyramids, structures which contain rooms with chests filled with valuable loot and a pressure plate that can activate TNT hidden underneath, should an unsuspecting player fall onto it.

[[Masahiro Sakurai]] stated that the Final Smash was inspired by seeing players create buildings filled with traps to harm their opponents, which consists of an act called "[https://minecraft.wiki/w/Tutorials/Griefing_prevention Griefing]": intentionally irritating another player. The first-person perspective seen just before the explosion resembles ''Minecraft'''s default camera mode, with the irregular movement characteristic of a computer mouse. Steve's crouching after the Final Smash is a common gesture in the ''Minecraft'' community used as a sign of friendship or, in this case, to mock a losing player as a form of teabagging.

**This makes it one of four Final Smashes to incorporate a pre-rendered segment, along with [[All-Out Attack]], [[Gigaslash]], and [[Supernova]]. Like them, the animation is rendered at 30 frames per second (likely as a space-saving measure), as opposed to the rest of the game running at 60 frames per second. The damage percentages are also absent during these attacks. Unlike the former two, the game can be paused during House of Boom's cutscene, a trait that is shared with Supernova.

***If the HOME menu is entered during the cinematic, part or all of the cinematic is skipped, leaving the modeled effects out of sync.

*Very faintly at the beginning of the Final Smash cutscene, it is possible to hear the 'Cave 8' and 'Cave 17' sounds that play in dark areas in ''Minecraft''.

*The explosion graphics during the cutscene are identical to those in ''Minecraft: Bedrock Edition''.
