アルフレッド・ヨードカス・クワック

Alfred J. Kwak is a duck. As a kid he lives in a giant clog with his family, later on he lives with his adoptive father Henk in a clog-shaped house. He is very concerned with other people. Although he has gone through a lot of sad things, his favourite song is 'Ik ben vandaag zo vrolijk' (I'm so happy today).
