It's the popular chocolate egg treat which offers children a tiny plastic toy inside.

But one adult Kinder Surprise customer was outraged when she discovered her mystery figurine was a little green bird striking a 'disgusting' pose.

The bird held a microphone in one hand, but it's what it held in the other that had the customer, Rachael, fuming.

'I got a Kinder Surprise and it is a green man TOUCHING HIS GENITALS,' she wrote next to a picture of the toy she shared on Facebook.

'WTF is this?! Children are exposed to this disgusting act - what has the world come to?

'It's f****** disgusting and clearly we are desensitised to these sort of things. F***** Ferrero who owns Kinder needs to look at this s***.'

Rachael, who doesn't have any children of her own, said the toy wasn't appropriate for youngsters.

The customer took to Facebook to vent her anger. She wrote: 'It's f****** disgusting and clearly we are desensitised to these sort of things'

'It was absurd. It is partly ridiculously funny, and also something that is not for children. I can't fathom who would think it appropriate for children,' she told Kidspot.

'Most people have agreed that the toy is not appropriate, and some have responded with confusion. Some see the funny side - even I do. There is a fine balance between ridiculous and what is very wrong and inappropriate.'

A Ferrero spokesperson told Daily Mail Australia the company did not intend to cause any offence.

'Each Kinder toy scrupulously respects European and Australian toy safety regulations,' they said.

'Each toy is subjected to a long process involving designers, technicians, doctors, psychologists, legal experts and commercial managers, with the aim to offer children a great toy that is safe from every point of view.

'Kinder strives to offer its consumers the highest level of product quality and safety, always respecting and exceeding the highest standards, to meet their expectations and ensure their satisfaction.'
