'90s kids, rejoice! The iconic theme song for Nickelodeon's "CatDog" was just brought back to life when YouTuber Triforcefilms uploaded a new video to his "Saturday Morning A Capella" playlist on August 22.

He records himself singing and humming 12 different parts (which you can see individually), while the theme song's familiar animation plays in the center of the screen.

Plus, he sounds 100% like the original singer's voice, so much so that it's kind of creepy — yet still awesome. If you need a refresher, here's the original theme song, in all its nostalgic glory.

And here's Triforcefilms's version. It's one of those videos you can watch multiple times, yet continue to notice new things.

Bravo! ? Now someone tell us how they poop.
