Like his female counterpart, Nigel-Night spends his days playing bingo and shuffleboard and posting on online dating sites. While posting on sites such as "Wrinkled Romance" and "Dimdating.dim", he is not always truthful about his age and appearance, and instead pretends to be a rich, handsome teenage boy, when in reality, he's old and spends all his money on prune juice and blood transfusions. Nigel-Night is portrayed as being very flirty and often aggressive towards the opposite gender, with other characters commenting that he has his "mind in the gutter". Nigel jumps at the chance for any kind of interaction with a female character, and is very keen on marrying someone new as soon as possible.
Nigel-Night looks similar to Denzel Crocker, with a hunch back and ears on his neck. He has white hair, a white beard, wears glasses, a blue shirt, green pants and black shoes. On some occasions, he wears a black tuxedo. His voice is similar to Filburt from Rocko's Modern Life.
