[Lego Batman] Is Joker a master builder?

As established by The Lego Movie, Batman (and several other DC superheroes) are skilled enough to be considered "master builders". In the new movie, Joker is able to convert Wayne Manor into a deranged carnival fairly quickly, but its unclear if this was completed by himself or with the help of his new army.

Or is this a silly question because Lego Batman and The Lego Movie are completely different playsets?

Lego Batman and Lego Movie are a shared universe. Lego Batman makes explicit references to the Lego Movie including the news reporters discussing the Infinite Abyss of Nothingness and showing a model of Gotham city on a table; also Batman tells the computer to activate Master Builder mode.

It's not clear if the Joker or any of the other bad guys are master builders, but it stands to reason at least one is.
