Be cautious of random cartoon streaming sites. Because Invader Zim is a cult show, many "free episode" links are often malware traps or have terrible audio sync. Support the official release so that Jhonen Vasquez gets his royalties (and maybe we can finally get that movie sequel).
In an attempt to make GIR useful, Zim upgrades the robot's guidance system. However, he forgets to upgrade the battery. The two are stranded in the city with no way home. This episode is a masterclass in visual comedy and pacing, featuring a scene where Zim uses a " Megaphone of Doom" to command a taxi. It highlights the show's love for urban decay and industrial noise. Invader Zim Full Episodes Season 1
