This seal is well-known among the people who live along the River Witham in Anton's Gowt, Lincolnshire, UK. He is called Dandy Dinmont (and he looks the role) and has been a resident since 2017.
Recently, Dandy visited a group of paddleboarders. Lincolnshire Live reports that he climbed on two of the boards and stayed there for about 10 to 15 minutes.
