From the Official Disney Parks Blog…
King Triton – who is Ariel’s father – has taken his place on top of the main archway in front of the upcoming attraction, The Little Mermaid ~ Ariel’s Undersea Adventure, in Disney California Adventure park. The statue itself is 76 inches tall. You’ll probably recognize him. He’s the same Triton who once appeared near the Little Mermaid meet-and-greet area in Fantasyland. He was moved when that space became Pixie Hollow. Walt Disney Imagineers knew the Little Mermaid attraction was the perfect new place for him. He even inspired the design of Ariel’s sisters as classic bas-relief figures on the archway’s face. They will complement King Triton on the arch.
