Lots of affirming messages. Eep and the rest of the Croods learn that hiding leads you nowhere, that courage opens up your world, and that love needs to be expressed. Also, to be yourself. As one character says: "Don't hide -- live!" Some bodily function humor (nose picking, etc.).
Some name-calling intended to be humorous -- "fat," "dummy," etc., plus "sucky."
Although the movie itself contains no product/brand references, DreamWorks has merchandise partnerships with everything from video game companies to tofu.
