Two boys in the bathroom with one naked at the sink and another in the tub. Eventually, the boy in the tub stands up and does a quick little comical dance.
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.
