It’s absolutely real. This behavior is well known among otters and has been documented in numerous serious studies.
It’s not uncommon to see otters playing music and making their own instruments.
Families of otters have been observed passing down the same instrument from generation to generation, making improvements to it over time. I have this example in mind of an otter that used to play the electric guitar, and we realized that this guitar had originally been made by one of its ancestors and had been electrified and modified as it was passed down to younger generations.
