- "Even those Logging Losers, no one will care if they're gone!"
- ―Walter Sliggs, Aura of Menace
Walter Sliggs is a pompous self-proclaimed oil tycoon.
Walter Sliggs inherited his grandfather's oil enterprise on Sodor and continues to expand it. He works with many of the Island's diesel engines, particularly Diesel, Dart, Den, and Sidney. He has many refineries and drilling sites scattered around the Island. One of his largest refineries was destroyed during the catastropic "Munitions Incident." He took it upon himself to berate Captain Grant for the Ministry's ineptitude.
Walter Sliggs was at The Mine Junction when D261 and D199 were sent on a runaway course towards his refinery there when they crashed into the barricade brilliantly set up by The Pack, Bertram, Gordon and his brother. He was left unscathed from the terrible crash but when he returned to Kellsthorpe Refinery, he was met by Sir Frederick Aura, who told him of a massive oil reserve beneath Ulfstead Castle that could be his if he helped Aura.
After some struggle deciphering the invitation, Sliggs attended the Fat Controller's meeting at Last Haven. He is quite distraught upon hearing the meeting is only an invitation for an invitation, upset that he cancelled his tennis lessons to attend the meeting. When the lumberjacks begin to rebel, Sliggs knocks down an aggressor with his tennis racket. Upon his aggressor pointing a gun at him, he runs off, disowning his colleagues in the process.
Main Article: Everyone and Walter Sliggs
Walter Sliggs is oily, rude, and completely self-absorbed. If he could describe all the positive features he saw in himself, it would take far too many hours before he felt like he had said all he wanted to say. He is obsessed with wealth and money and it is apparent he has not washed his hair for several months. He also refuses to wash his monocle, despite the fact that it would improve the vision in his right eye if he did.
Despite his rudeness all he desperetly wants is friends.
Walter Sliggs absolutely despises tennis, but insists on purchasing lessons anyway.
