Plankton is the tiny green villain from SpongeBob SquarePants, the long-running Nickelodeon series created by Stephen Hillenburg that first aired in 1999. Obsessed with stealing the Krabby Patty secret formula from Mr. Krabs, Plankton is constantly scheming and constantly failing, which is why his frustrated groans fit troll and prank edits so well online. Clips of his voice have circulated for years in meme edits and soundboards, where the drawn-out ughhhhhh is reused whenever a plan collapses, someone gets teased, or a reaction needs exaggerated annoyance instead of a short sigh.
