Thanks to DemonLouie. This is the cartoon that I was talking about.
Mr. Bogus was that cartoon that I watched as a child. Lasted for 3 seasons long, and the clay animated segments are really short, like 20 to 30 seconds long, before the cel-animated segments are shown off the whole episode. If there is the english episodes that I could watch, without no VHS noise distortion involved that I've found on youtube. Please tell me what website that I could watch the episode, where he and his cousins are on the beach.
