|First Appearance:||The Neverhood|
|Voice Actor:||Mark Lorenzen|
Willie Trombone is Klaymen's cousin, and one of the sons of Ottoborg. Willie is not very intelligent, and has a ring on the top of his head. It is common for the ring to be caught around tree branches.
When Ottoborg's World fell apart, Willie's chunk consisted of his red roofed house. Willie soon came across some Victoids. The Victoids thought they would have to be clever to trick Willie into eating him. However they were wrong because Willie is extremely dim-witted. Bil soon came and saved Willie from the Victoids. Willie then dined on Victiods for months. Soon Willie and Bil meet Hoborg and the three went to collect klay. Once they got back, Hoborg included Willie's red roofed house in the Neverhood as part of the cannon monument.
During The Neverhood Edit
When Klogg overthrew Hoborg, Willie found a life seed which he used to create Klaymen. Willie then left several disks behind to tell Klaymen what to do. When Klaymen climbs in Bil, he notices Willie being attacked by a Weasel. Bil then saves Willie and Willie climbs in. After Bil and The Clockwork Beast's fight, Willie and Bil fall off of the Neverhood. However, Hoborg brings them back.
