Stream cartoons Invader Zim Episode 9 The Wettening During a rainstorm after school, Zim discovers that water has a harmful effect on his Irken skin. Dib also learns this and over the weekend he constructs an automatic water balloon-launching weapon to destroy him. Zim realizes he must defend himself and he discovers that paste protects his skin from the harmful effects of water. On Monday morning, Dib turns up at school with his weapon, and prepares to annihilate Zim—but when he attacks, he finds Zim has been replaced with a holographic decoy. Zim is in fact on a space station with his own over-the-top water-based weapon. The space station siphons all the water on Earth (Including all oceans, lakes, and rivers) and into a massive water balloon of his own, which he subsequently drops upon the Earth—causing apocalyptic flooding and destruction and him taking over the world (though no major characters are harmed). The whole water balloon plan was to kill Dib (and possibly any other Zim finds annoying, the more humans gone, the better), but, as usual, Zim goes completely overboard. At the end, Zim marches off to what’s left of his base, saying he’s going to immerse himself in paste.
