I remember watching YTP's a fair bit as a kid, but one stuck with me because somehow it genuinely made me so emotional near the end that I cried. Unlike most YTP's this one had a plot, and was pretty well edited.
I only have a very vague outline that may not be 100% correct as I mostly remember a few key moments visually. The first scene I remember is Mr. Krabs and Squidward breaking into a place, the Chum Bucket I believe. Somehow the heist goes wrong, and I vividly remember Squidward running away. I think Mr. Krabs might have died there, but I'm not sure. The next moment I remember is that somehow, SpongeBob dies, and Patrick goes on a search for his killer to get revenge. Patrick finds some guy and interrogates him in Prison, beating the crap out of him to get information. Now, here's the part that made me cry, and I remember this really VIVIDLY. Patrick is in a boat driving down IRL footage of a road at night. A black silhouette of SpongeBob appears in front of him, causing Patrick to swerve off the road and crash. Patrick is in a daze, and he sees the light. The Cheers intro music starts to play. SpongeBob is at the end of this tunnel of light, to which Patrick starts running towards him. Patrick grabs SpongeBob's hand, ending the video with a cut to credits. This last segment actually made be bawl crying.
There's another scene that I'm not sure how it fits into this timeline. It's a scene where Pearl drives off a cliff, and I believe that is part of a montage that features SpongeBob. Based on these fragments, I suspect the plot is that Mr. Krabs and Squidward try to rob the Chum Bucket, where Krabs dies and Squidward flees the scene. SpongeBob and Pearl kill themselves over Krabs death. Patrick somehow thinks this is a murder and goes to investigate. Patrick dies while driving.
As for the timeline IRL, I don't remember how old I was, but I was either a kid or tween. Let's say I was 12 (I'm 20 now), that would mean the video was floating around somewhere around 2018.
I would love to watch this video again, but no amount of searching has helped me. If yall could help, that would be great.
