Two 12-year-olds dance together on the beach, in their underwear. They decide to "French kiss" each other and then the girl invites the boy to touch her chest, which he does, and she comments that she thinks they will get bigger. At this point they embrace, and she says "It's hard", implying he has an erection.
2 boys (both about 5) and 2 girls (approximately 5 and 7) are jumping up and down completely nude in a trough outdoors. When a band starts playing, they climb out of the trough and dance around nude in a circle.
Anna-Maija (Tia Moilanen, 7?) and Marja (Anna Erkinheimo, 7?) take off their clothes and examine their naked bodies using handheld mirrors, while being spied on by a boy of their age.
