Faygo may not be as famous as Coca Cola or Pepsi, but back in the '90s the company licensed Super Mario to appear on some of its beverages. Fast forward to today, and the firm's Instagram account has just triggered a wave of speculation about a possible undiscovered Super Mario Easter egg.

The post is question shows some of the Super Mario-branded drinks from the past, along with a rather cryptic message:

What would you say if we told you there was a Faygo Easter egg in the game that no one has found to this day?

As you can imagine, this has caused some to speculate that Faygo knows more than it's letting on; could an unearthed Easter egg really exist in a past Mario adventure? 

The containers shown in the photo date from around 1993, and the closest Mario outing to that is Super Mario All-Stars on the SNES. Could that game contain a secret, or is this simply a case of Faygo's social media team stirring things up to create awareness around the (rather obscure) drinks brand? 

You decide, and after you've done that, be sure to post a comment below.
