Phil Phillips makes a few mild sex references.
A female puppet flirts with a male puppet and puts her foot on his shoulder and then licks his face with a very long tongue; then they make out on a desk and then against the frosted window of a door (there are people on the other side of the door that hear and see the female puppet being pressed against the glass) followed by an extended ejaculation and we see silly string spraying all around the room, on the ceiling and the walls. Pretty tame and it's a PG-13 sex scene
A female puppet's pubic hair, is shown in close up during an interrogation scene (a parody of the scene in the movie "Basic Instinct").
There is a scene that takes place in a covinince store where an octopus rapidly milks a cow. The octopus increasingly milks her and moans suggestively while the cow moos orgasmically. Not graphic and brief
The sex scene is very brief and there is no nudity. The entire scene is in the red band trailer.
