In 1984, Erika Brueggemann was working at Schweizer Fernsehen (the German-speaking division of SRG SSR) when she was introduced to animator Otmar Gutmann.

Gutmann was not immediately convinced, since he had already created many sea lion characters out of plasticine, but he eventually pushed forward with the penguin idea too.
