This is the episode where Sokka officially suggests the name "Team Avatar" (though he also suggests "The Aang Gang" and "The Boomeraang Squad"). Plot Summary
Aang faces off against Azula on top of the drill. In a final, iconic move, he uses a combination of earthbending and airbending to deliver a massive blow, causing the build-up of internal pressure to explode the drill from within.
Sokka realizes they don't need to destroy the whole drill—just the braces connecting the inner and outer shells. While Toph slows it down from the outside, Aang and Katara use waterbending to cut the internal supports.
