Unfortunately, there does not seem to be a consensus of answers for the cheat or password into Mighty Guy 3 on Funbrain. According to some of the sites the password is DOOD3. Another said that Queen7 would work. However, after looking at Funbrain.com I could not determine whether there is even a Mighty Guy 3 game out there. According to posts from four years ago there was a Mighty Guy one and two, but even these did not seem to appear on the site.
If the above passwords do not work or you cannot find the game anymore, you may consider trying some of the other options on Funbrain.com. There seemed to be plenty of games for the K for grade eight age. The games are centered on the age group to make them simple and easy to understand. The site is meant to be a place to learn as well as have fun.
Upon testing out the site, it seems that you can play the games without registering any personal information. It did ask for a password for a returning user, which I assume one obtains if they leave the game properly and wish to come back. Mighty Guy 3 did not seem to be part of any of the games even after clicking on all games. It was also not found when searching Google directly. This leads me to believe that the answers from four years ago on other sites are accurate and the game does not exist. If you want a password into other games on the site you may have to become a new player and then retain the password you are given once you leave one of the games after play.
