Phinny (voiced by Yonas Kibreab) is a main character in Pupstruction. He is a 7-year-old Welsh Corgi who is the captain and architect of the Pupstruction crew, the smallest, and youngest of the crew. His vehicle is a crane. Phinny's catchphrase is "Let's crank it up." Sometimes, Phinny will ride around on a bone-shaped skateboard. Whenever a character laments that some action cannot be done, Phinny would see it as a good idea, and make use of it.
