SpongeBob woke up, he brushed his teeth, he fed Gary and went off to the Krusty Krab. He sees a dark glitchy liquid with an emoji for a head slither by, but doesn't think much of it. He eventually goes to the Krusty Krab and goes to the kitchen.

SpongeBob: don't know what that dark glitchy thing was, probably just one of Plankton's inventions.

he laughs as he brushes it off.
