"(づ-ʖ-)づ" is an emoticon commonly used to express a hug or a feeling of excitement. It features a face with a mischievous expression and two outstretched arms forming a hugging gesture. "He is a sleepwalker" is not an emote, but rather a statement indicating that someone is prone to sleepwalking. Sleepwalking is a condition where a person walks or performs other activities while asleep, usually without any memory of the event upon waking up.
