Tear Jerker / The Brave Little Toaster to the Rescue

• After being egged on by Kirby, Sebastian undoes the bandage on his arm and shows him the result of the horrors he endured from being an involuntary test subject. We only see the shadow and everyone's shocked reaction, and Kirby's arrogance immediately gives way to sorrowful humility as he tells Sebastian how sorry he is, tears in his eyes.
• "Chomp and Munch". The characters are watching Wittgenstein, an outdated computer, dying before their very eyes. Wittgenstein's Back Story is pretty depressing too. He was once the most famous supercomputer in his time, but once modern-day computers came along, his creators shut him down and unceremoniously stored him in the basement to be forgotten. It's probably the only song in the sequels that matches the emotional impact of the ones in the first movie.
• Later, Radio's Heroic Sacrifice. He basically took his own heart out.
