Tofu Boy is a PC/Mac/Linux exclusive joke character originating from the titular main protagonist in PETA's parody of Super Meat Boy, called Super Tofu Boy. Tofu Boy has an inflated ego, and is not actually as effective as he thinks he is.
With the lowest speed and jumping height of all characters due to a "major iron deficiency", Tofu Boy is virtually useless. He is incapable of beating almost all levels, even being incapable of completing the first level without the use of the alt glitch. However, completing any level always awards the player an A+ no matter how much time it takes.
Tofu Boy was added as a playable character on December 8th, 2010. He can be playable by typing "petaphile" in the character selection screen, then selecting any character at the character select screen. However, one must be fast to get this done correctly.
Typing in the code for Tofu Boy awards the player with the "Well look at you!" achievement. This achievement is only available in the Steam version and Ultra Edition of the game.
In Super Meat Boy Forever, Tofu Boy can be unlocked by collecting all 60 pacifiers. His disadvantages from the previous game carry over to here, but replacing his poor air control (since the player no longer has full control over their direction) is the fact that, when grounded, he will come to a complete stop to catch his breath at regular intervals. During this period, the player cannot control him at all nor make him get up faster, leaving Tofu Boy virtually helpless to the following hazards if he does not get up in time:
Tofu Boy's many vulnerabilities, coupled with his slowness and low jumps, make him remain a poor choice for every level. Should the player complete a level with him, they will unlock an achievement.
