Hidden details in films and video games are known as 'Easter Eggs', and while they aren't as cool as chocolate, they're pretty sweet when you find them. Disney Pixar is notorious for the extra amount of details that they put into their films.

'Toy Story', 'Onward', 'Coco' and 'Wall-E' have all been incredibly popular Pixar films within the Disney franchise and are all FULL of Easter Eggs. These tiny details also often translate into pop culture and REAL LIFE, and they're super exciting to find!

A year ago I was in a Wal-Mart in Phoenix, Arizona and was checking out the clothes when I saw a white t-shirt with a red Pizza Planet logo. It looked so familiar, but I couldn't remember ever eating at a Pizza Planet or where I recognised the logo from.

It was in that moment that I realised Pizza Planet is the pizza store in 'Toy Story'. The imagery and logo sat in my subconscious for over 20 years and it was pretty awesome finding a real life Easter Egg!
