Clyde Flynn is Linda Flynn and Tiana Webber's father, Phineas Flynn and Candace Flynn's grandfather, Lawrence Fletcher and Bob Webber’s father-in-law and Ferb Fletcher's step-grandfather. He lives in Danville's woods and hosts Camp Phineas and Ferb. He is not a very good bugler, but loves to sing and entertain the children. He often tells stories that he heard in his childhood like Bigfoot and Badbeard. He is not only a story teller, he is a color commentator as stated by Phineas for the roller rink commentary, but rather than adding "color" to the information, he actually said the names of different colors (Clyde: "Red, green, blue!" Phineas:"Excellent colors, grandpa") ("Crack That Whip").
