"*ominous silence*" ~ Diddy's only observed state
Little is known about Diddy beyond its striking resemblance to the Nintendo character Diddy Kong. Diddy does not seem to be an entity that can be defined by our conventional methods of categorisation. It has no gender (although it is often referred to as "he") nor does it possess any characteristics that would justify the use of neutral pronouns. Diddy isn't a "he". It is isn't a person. It is isn't even necessarily sentient.
Diddy simply, is.
“I have come to believe that the whole world is an enigma, a harmless enigma that is made terrible by our own mad attempt to interpret it as though it had an underlying truth.”
