Remember in The Chaperone where SpongeBob says "I couldn't even get a date for my own Junior Prom?" Does this imply that in season 1 Pearl was in between 11-13? Or did SpongeBob imply "junior prom" as Pearl's junior year of high school? Honestly, the first one could make sense since Pearl didn't turn 16 until Whale of a Birthday. But I dunno, SpongeBob probably meant 11th grade and not 6-8.
