Sooklek was first popularized as the titular role in the cartoon series Prince Chantarakob (จันทโครพ) and eventually became a public personality as creator Prayoon used the character in his satirical cartoons.
When Field Marshall Thanom Kittikachorn gave out an order for Prayoon to stop his political cartoons in 1968, Sooklek was drawn with lips sewn together.
