Name two characters that encouraged kids to eat more veg during ww2?

"Potato Pete" was one. The other, I think, was "Doctor Carrot".Onions were hard to get, and carrots considered horses food. The minister of food wanted people to eat more carrots, and also to stop the Nazis finding the secret of radar, so he put it abroad that carrots enabled people to see in blackouts and night-time RAF pilots to see in the dark too. Which was a sort of half-truth. But people hated carrot cakes. Don't forget that about the time of WWII, Popeye gave up his whiffle hen and began eating spinach for his strength.
