Sir Ebrum is about two to three times as big as Tiff and Tuff are. He has yellow skin and eyes. His hair is purple, as is his moustache, which has a British look. His outfit consists of a purple jacket over a white shirt and red bow-tie and (despite his masculine gender) a brown "skirt".
Sir Ebrum is a bit clumsy, thus gaining a comical reputation, but he does care for his family.
Sir Ebrum may have earned his name from Cerebrum (the part of the brain that controls the thought process. This comes from the Latin Cerebrus, which meant "Brain" in general.).
