Attending Berk's 400-Year Anniversary
Whispering Waldo, along with his brothers, Mute Marvin and Soft-Spoken Sam sailed a long way to join their nephew, Silent Sven on Berk to celebrate Berk's 400th Anniversary. At this time Hiccup also had a bounty on his head, placed by Viggo Grimborn or the Dragon Hunters. With this weighing heavily on his mind, Hiccup mistook the "ship-lagged" uncles to be bounty hunters after him. Sven corrects his mistake, and Hiccup awkwardly welcomes Sven's family to Berk, and calls Whispering Waldo, "Wailing Waldo".
Whispering Waldo is bald with a reddish brown moustache very similar to Sven's. In fact his whole appearance is very close to Sven's appearance and build. At the Anniversary celebration, Waldo wears a simple red tunic.
