|“||YOU SHALL NOT PASS!||”|
— Lego Brick, BFDIA 5b (Level 33)
Lego Brick was a recommended character by "Bkshawgogo", who placed 1st as a recommended character in the second episode of BFDIA. He is known for his very happy smile. Due to his shape and color, Book initially thought Lego Brick was a armless mutant, deformed Blocky.
In BFDIA 5b, after he got killed by Book trying to pass a level (level 32), as a revenge, he trapped Book and Match behind a wall he said he rented for a week (level 33), then trapped them in his dungeon/factory. Ice Cube was also found in the dungeon/factory for an unknown reason (level 42). However, Match, Ice Cube and Book had escaped the dungeon/factory. Later, they saw Waffle and he told that Lego Brick was a nice guy, but he had 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). Apparently, 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.
This section is a work in progress; due to Lego Brick's minor character status, sections will be filled in when they appear on other characters' pages.
In BFDIA 5b, when Book encounters Lego Brick, she calls his appearance horrific. Then, Lego Brick offers to be friends. In the next room, Book needs him for something, which involves killing him and trapping him in a box, one of which is a huge fear of his. As revenge, Lego Brick drops Book and Match into his underground factory. Later, Waffle explains Lego Brick's fear of dying to Book.
- Lego Brick is the second person that is shown to own an underground factory, the first being Golf Ball.
- Lego Brick's pose was also reused for Rocky's elimination pose in Zeeky Boogy Doog.
- As said above, Lego Brick was revealed to have a fear of dying (thanatophobia), which later answered his anger towards Book and Match after the latter killed him.
- Lego Brick is playable within 5b's files and coding.
