The Sombrero Guy is a mysterious figure who appears randomly throughout the series. So far, he has appeared in "Life Inside a Console", "Eyes of Skull Has A Secret", "What The Hell Happened To Mega64?" and "Delaware". The Sombrero Guy's arrival is often made with mystical music being played, and he always shows up unexpectedly. He doesn't appear to have much of a personality from what viewers can deduce from his hodgepodge appearances. He always has a long monologue which is suspiciously conceived immediately prior to his arrival. The Sombrero Guy has offered ambiguous advice to Rocko and Derek, yet goes unheeded, due to his sudden inexplicable arrival. He interrupts Dr. Poque's internal monologue with his own, and is scolded in "Eyes of Skull Has A Secret."
