In a state-produced propaganda film produced to capture this significant moment, they endure many tests from their superior Kowalski, including their ability to withstand comically exaggerated harm and 167 days of isolation where Ren pretends to eat Stimpy to cope with hunger.
It is the duo's turn, with Stimpy defecating in his suit; the tube is connected to Ren, who narrowly avoids being covered with feces by having Kowalski grab them in time.
Ren devises a plan to steal fuel from the Americans; Stimpy accidentally plugs the wire into the septic tank, causing one of the pigs, who was defecating, to be sucked into the Russian spacecraft.
The duo are heralded as the winners of the space race as part of the United States, eating all the corn they can while being cheered on; the American pig is "celebrated" in Russia on a platter, ending the episode.
[1] This is the first episode to feature Phil Hartman in a cameo role, in multiple attempts by showrunner Bob Camp to reinvigorate discussion of the series with guest stars; he would appear again in "Stimpy's Pet".
