In Horror Land, it's a bad idea to pay him ten Coins to Big Mr. I, but not only it wastes the character's money, but he'll roll into a character and force them to run away and landing on a Mr. I space will make him stop. The game forces the character to run away if he's on his laser route.
His Mr. I Laser is a weapon in the garage and he never appeared.
After absences from the Game Boy Advance and Nintendo DS versions of Mario Party, Big Mr. I made his final appearance in the game. He appeared in the mini-game Eyebrawl as the third Mr. I along what appears to be a double or duplicate. A character must use the Wii Remote to rotate the pointer on-screen until becoming Mr.. I becomes dizzy and disappears. Big Mr. I was later re-styled.
