"Perhaps it's the backpack that makes Sammy this way!” -ChadtronicThe Mario Backpack is a backpack that is designed to look like the character Super Mario from the video game series of the same. The backpack is often worn by SammyClassicSonicFan in his YouTube videos.
The backpack has the shape and appearance of Mario as well as dawning two red straps to be used for carrying on one's back.
Although unconfirmed, Chadtronic has speculated that the cause of Sammy's rampage may be because of this backpack.
Limited Edition Extra Rare Fire Mario Backpack Edit
Additionally, the Mario Backpack has a variant called the Limited Edition Extra Rare Fire Mario Backpack (also a newer parody account). The backpack is incredibly valuable, and is said to behold supernatural powers. As we see in the Sammy video "SammyClassicSonicFan's Adventure," the backpack is capable of allowing the beholder to shoot large fireballs. It is unknown whether or not the backpack contains any other powers.
