9-year-old Maddox and 7-year-old Pax carved Jack-o-lanterns with their classmates on Friday at the Lycee Francais de Budapest.
As for their costumes, an insider has said that they "sketched out the types of costumes they liked" and put them together themselves with their nannies.
The Jolie-Pitts had "a little dress-up party" for the kids on Sunday, where Pax dressed as a mad scientist, and 5-year-old Zahara dressed as "a spring fairy."
Maddox wore an "all-black chimney-sweeper-like outfit."
Here's what an insider had to say about Maddox's costume choice:
"He is obsessed with black colors [and] loves the brush they carry."
