Freaky pink primates!

Why 'pink' ? What is the exact meaning?

It was in Over the Hedge.

All the characters in "Over the Hedge" are animals.

Imagine you were an animal and all the beings you've ever been exposed to are other animals. Then you see human beings for the first time. How would "they" appear to you?

Freaky, pink primates.

Monkeys, which the film's characters are familiar with, are all black because of the hair covering their bodies.

This is the first time "pink" monkeys have ever been sighted – monkeys with no hair.

This is used to describe humans - the humans seen are caucasians.

The speaker, being an animal, identified humans as a type of primate, and the adjectives 'freaky' and 'pink' are pretty accurate in this context:

• Freaky meaning different or odd
• Pink meaning, well, pink skinned
