Footbomb was a goblin sport usually played on Kezan. In the game, goblins sit in shredders and kick footbombs onto the opponents' shredders to destroy them (which may or may not be part of the normal game). Then, they need to kick a footbomb into the opponents' goal. The last Footbomb match was played by a goblin adventurer, who kicked the footbomb into Mount Kajaro, during the exact moment when Deathwing caused the mountain to erupt.
The Coin-Operated Crowd Pummeler can summon Azerite Footbombs.
