'Rick and Morty' Season 5 Episode 4: Morty's Sperm on the Loose

Rick and Morty reached new heights of ridiculousness in the latest episode "Rickdependence Spray" as they battled giant killer sperm with the help of an army of cannibalistic horse people.

Season 5 Episode 4 didn't try and find an emotional resolution like previous episodes and in all honesty it would have been pretty difficult given the 22 minutes of insanity that preceded the low-key ending.

Creators Dan Harmon and Justin Roiland shared the voice acting responsibilities with some notable guest stars in this episode, with the likes of Christina Ricci (Black Snake Moan) and Kyle Mooney (Brigsby Bear) voicing colorful characters.

The story moved so fast and the one-liners were non-stop so we'll try our best to explain what the hell happened in "Rickdependence Spray."

What happened in Rick and Morty Episode 4?

There's no delicate way to explain the plot so we'll just dive right in. Shameless teenager Morty spends a week inserting his own seaman into a horse breeding machine at Beth's work.

He's seen congratulating himself as a "dirty little doggy" before noticing that his grandpa Rick is wheeling in a barrel of horse seaman for an experiment but Morty knows his own seed lies in there.

Too ashamed to admit his deed, the horse seaman barrel explodes creating a race of giant killer sperms. For a long time no-one knows where they came from and Rick and Morty are asked by the president to destroy the "orgazagoblins," "cumplestiltskins" or "skeetboogins."

Once Rick and Morty track the giant sperm to the Grand Canyon, who have gathered there for obvious reasons, they're confronted by a talking queen sperm who reveals to Rick that Morty is their father. They pin him down and extract more of his seed using the horse breeding machine from Beth's work.

Meanwhile the president, Summer, Beth and Jerry form their own plan to stop the sperm by creating a giant human egg to attract them in Las Vegas.

Rick and Morty and a friendly sperm called Sticky are captured by a race of cannibalistic horse people known as chuds. The chuds are about to kill and eat the trio before Princess Ponyetta saves them by revealing she's pregnant with Rick's baby.

We told you this episode was hectic.

The giant egg in Vegas was taken from Summer, so everyone is now worried that the sperm will reach the egg and create a giant incest baby.

A truce is formed between humans and chuds and they unite to battle the sperms in the glamorous surroundings of Las Vegas.

In the nick of time, Sticky defeats the queen sperm before she can reach the egg but Sticky heads inside anyway. Luckily the president rigged the egg to shoot off into space, meaning the giant incest baby is space's problem now.

Princess Ponyetta gives birth to her child, which is in fact a Rick-horse hybrid but since they come out fully formed, the baby burrows into the ground and the inter-species lovers part ways.

The episode ends with Rick staring deadpan at the camera, and presses his red button which blankly says "that was easy."

Beth and Summer share a poignant B-plot throughout as Summer learns that women are constantly overlooked and not given credit when it's due. This seems incredibly appropriate in an episode where a potentially world-ending problem all comes from the sperm of a teenage boy.
