Mario goes back in time to ancient Egypt! Now he thinks he's an assassin and tries to parkour around Egypt.
As a museum opens its Egyptian exhibit, Peach, Toadsworth, and Luigi marvel at the attractions there are to see. Luigi is amazed at the sarcophagus and takes a closer look at it. Only for the sarcophagus to open and reveal a mummy inside. Luigi runs off scared as the mummy falls to the ground. He hides behind Peach in fear of what just happened. Mario comes out behind the sarcophagus and laughing at Luigi after pranking him. Toadsworth reminds Mario that he told him not to tough anything. Mario again laughs it off by taking off his clothes and throwing them to Toadsworth. Peach has had enough and so decides to chain Mario up with Toadworth holding the leash. Mario then notices a flashing orb and decides to take a close look at it. As he gets closer to the orb, it intensifies and starts to create a weird background vortex behind it. As Mario is about to touch it, Toadsworth sees what he is doing and pull on the chain leash, causing the leash to extend so Mario can't touch the orb.
As Peach and Toadsworth are distracted by looking at an artifact, Mario discovers that he can be freed from his chain leash, to which he does this successfully. Mario goes off and then stumbles upon a mask. Mario runs around with the mask on saying that he's a hobo, also commentating that it's hard to see with it on. During this, he accidentally knocks over the orb from earlier, causing it to roll aside and to open a portal. Mario is unfortunately sucked into the portal as it closes after his entry. Peach and Toadworth turn around and see that Mario is unaccounted for, causing Toadworth to go on a cursing rampage.
