— Lego Brick, BFDIA 5b (Level 33)

Lego Brick is a recommended character by Bkshawgogo, who placed 1st as a recommended character in the second episode of BFDIA and had a role in BFDIA 5b.

He is known for his very happy smile. Due to his shape and color, Book initially thought Lego Brick was an armless and mutated version of Blocky.

In BFDIA 5b, he gets killed by Book who was trying to pass level 32. As revenge, he traps Book and Match behind a wall he claims to have rented for a week (level 33). Then, he traps them in his dungeon/factory. Ice Cube is also found in the factory for an unknown reason (level 42). However, Match, Ice Cube, and Book escape the factory. Later, they meet Waffle, who informs them that Lego Brick was a nice guy, but has a fear of dying.


Lego Brick seemed nice before Book killed him. After his death, he was extremely annoyed and angry at Match and Book for killing him (in BFDIA 5b). According to Waffle, he is generally passive, but he has a fear of dying, so he will be defensive in the cases he may die.



Now you know not to mess with me!
