Infrequent, very mild innuendo. Truffles at one point teases her husband, Mung about "getting cooking", and when they walk off in the opposite direction, Chowder says "Where are you guys going? The kitchen's over here!"
Very, very hidden strong sex reference in one episode.
Endive has a crush on Shnitzel
Panini has a crush on Chowder. She often explains about how much she wants to marry him and have a lot of kids with him.
There are a few innuendos scattered here and there which may go over kids heads
In one episode, Schnitzel tells a joke which causes Mung to call him a "naughty boy", when Chowder begins to ask questions about the joke, Mung tells him that they will talk about it when he's older
Butts are seen a lot of times (suggestive)
Some belly jokes here and there.
Chowder lifts his clothes up and starts twerking and his bare butt cheeks are shown and bouncing with the words: Sweet on them. Mild since there's bare butt nudity shown quite a bit.)
Overall: 6/10 in this category, there's a lot of strong innuendos hidden that would normally fly over children's heads but sometimes they could catch on. There's also bare butt nudity, they're all moderate - mild. For more older pre teens like 10 - 12.
Chowder's bare butt is shown like a billion times.
