Peppa Pig is a cartoon character who is a pig and lives in a family. Somehow, when her father snorts, he creates a 7.5 on the Richter scale, and her brother is almost the equivalent of calliou but not as annoying and bratty. Peppa's freinds don't seem to show any liking towards her, and will probably betray her in high school (if she ever grows up).
Person 1: Hey look! It's a pig!
