- "Somewhere above him, Hermione whispered, “Mobiliarbus!”. The Christmas tree beside their table rose a few inches off the ground, drifted sideways and landed with a soft thump right in front of their table, hiding them from view."
- — Usage of this spell in the Three Broomsticks[src]
Mobiliarbus was the incantation of a charm that enabled a witch or wizard to levitate a wooden target a few inches off of the ground and then move said object in any given direction. It worked on trees and wands.
On 18 December 1993, Hermione Granger used this spell to move a Christmas tree in The Three Broomsticks to hide Harry Potter, because Minerva McGonagall didn't know that Harry sneaked into Hogsmeade.
