Li'l Sweet & The Doctor

Two mascots/advertising characters for soda Dr. Pepper team up for a duet in a 2020 tv commercial for the new flavor Dr. Pepper & Cream Soda.

Just so you know, Dr. Pepper is neither a Coke or Pepsi product, but is owned by Dr Pepper Snapple Group, a subsidiary of Keurig Dr Pepper. It was formerly part of Cadbury Schweppes Americas Beverages.
