In season one, a girl (aged 12), is shown in her underwear a number of times. In episode 4, her skirt gets ripped off by a cat-flap, resulting in her both standing in (and slightly pulling down) her underwear.

A girl "moons" her friend for a joke. We see her butt for a few seconds.

Very little and mild profanity throughout. Mostly mildly rude comments about going to the bathroom.

At several parties, teens and adults can be seen drinking (something) that looks like alcohol.
