As you've likely noticed Nintendo games tend to have fun and silly secrets. That's part of their charm, of course, and it keeps us busy with games long after they were originally released, one example being Super Mario 64.

It's only part one, too, which means there'll be more secrets in the future; yeah, we know, it's almost too much to handle.

So, check out Alex's vid - with a few cheeky lines - below.
