Disney and Pixar's big prequel to 2001's "Monsters Inc." came out last weekend.

"Monsters University" had a great opening weekend debuting to $82 million.

While most were excited to see the duo of Mike and Sulley (Billy Crystal and John Goodman) reunited on screen together during their college days, others were probably più excited with the thrills of the hidden gems in any Pixar flick.

Pixar is notorious for hiding a few iconic symbols in each of its films along with a hint at its successivo movie.

Disney publicly released a few of these little Easter Eggs along with high resolution photos.

Check them out below along with a few others we've compiled from around the Web and with our own eagle eyes.
