Here is chef Benji cooking on the cardboard stove at Nana’s house. I drew this with many references to the real one in the kitchen, so it has lots of details. I don’t know if you can tell, but in the top picture, he carefully “turned” the burner knob while making a ticking/whooshing noise quite recognizable to any user of a gas stove.
The chef likes to make (paper) fish fried in (imaginary) butter, (imaginary) tea, and car soup, all of which he serves on brightly-colored plastic plates. It looks like when I took these pictures, he also cooked some big plastic Easter egg omelette – yum.
