Pucker Uppenheimer is a minor character in The Loud House.
He first appears in "For Bros About to Rock". He and his band come to the Royal Woods Mall for a concert, and Lincoln and Clyde assist for being their first concert. At the end of the episode, with the help of Luna, the kids manage to reach the front side of the stage with Pucker and the rest of SMOOCH members, and obtain their best and unforgettable first concert.
His second appearance is at the end of "Yes Man", as he gets a call from the Loud sisters to come outside so Lincoln can still meet SMOOCH, but Lisa's giant spider from the VR simulation scares everyone away when it crawls out of the house and onto the roof.
Pucker is a slim man, with fair skin, and black long hair. His rock attire consists of a red tank top, a black vest, black pants, and black platform boots with three white spikes each one. He uses red lipstick, and has one black-and-red bracelet on each arm.
