They usually help Bling Bling boy to move his evil plans forward or (much to their despite) to build an invention to trap, catch or steal Susan Test or make her fall in love with him. they often warn Bling-Bling about the flaws or the events that might happen to him after using the invention, which he never pays attention to them. they also like being challenged by the Test twins on inventing something better to fight with. (Johnny vs. Bling-Bling: The Ultimate Battle)
They all have a yellow coat with a "B" sign (for "Bling-Bling Boy") on it along with black jeans and shoes.
- As they announced twice in My Johnny Guard, they hate their job.
- As they said in Johnny Test's Quest, they got sick and tired of the fact that Bling Bling always wants to catch Susan and said that they want to invent stuff for their own goals. but as soon as their plan failed, they decided to reunite with Bling-Bling boy to catch Johnny and his sisters for him (which they failed as usual).
- They also appear in Johnny Of The Deep in their cameos.
