Return of the Ehhs
Mario is somewhat hot-tempered, and when mad literally tosses the other characters around. But, deep down, Mario is kind-hearted and will help anybody in need. He is arrogant, cocky and not very concerned about anything except how awesome he looks. He also has many outbursts of anger and random fits and screeches. He seems to love his brother although, he does also laugh at his incompetence to not stop believing in little things, like Leprachauns, and Santa. Jack is a completely different story, as he normally despises Jack in all ways possible. He also loves to fight and will always give up one thing for a great fight. Pizza is the main dish of Mario's life, and he didn't even care when Kermit returned from the dead, just before a box of pizza came to his house. He concerns little to nothing of Peach, and others, besides his brother and bad guys. He normally kicks everyone around like a tin can, and makes them do things for him, and what-not.
Behind the scenes
|“||lol yeah his head fell off. So we had to glue it back together...||”|
— Tyler on his channel, in response to a user asking if Mario's head was glued.
Sometime before the filming of Mystery of the Stolen Hat, Mario's head came off. This is probably because of the numerous times of walking or jumping "the Mario way" in which he is thrown a far distance. Despite this, the tradition continued and can be seen after Mystery of the Stolen Hat.
In the reaction video to Summer Fun 2, Tyler and Kenny said that Mario's arms can't be moved anymore because some of the superglue dripped down on his arms when they were putting his head back on.
- Mario's eyes can be seen changing in Mario's Illness.
