I forgot one hand drawn picture! This should be the last now. It is not really a crossover from another cartoon, but somehow a crossover from a music video! See the video Green Jelly – Three Little Pigs and enjoy the music, the image I used is at 4’44! The three war pigs are Trapjaw, Triclops and Stinkor, and they are looking at Skeletor, who is the wolf in this story. He is bleeding, and we will never know what happened here.
Look at the shadows, have you ever thought Triclops’ head looks like a cowboy with a hat?
