Pekka ja Pätkä sammakkomiehinä

Directed by Armand Lohikoski

With Esa Pakarinen, Masa Niemi, Siiri Angerkoski, Sirkka-Liisa Wilén and Armas Jokio

Pekka Puupää and Pätkä, who return to Helsinki from an unsuccessful variety show tour, are forced into refresher training, where they are trained as frogmen. During the diving exercises, the friends encounter the mermaid Helmi, whom they help into the bathtub at home, to Justiina's shock. The friends, who have become civilians, eventually end up on a plane bound for Suez, being cornered by UN soldiers.
