The multiple oranges in the chocolate box may be some of the Million Clones. However, this is doubtful as the clones should've been given to the first one million susbcribers but nothing says that the clones were not more than one million. However, it could be that Orange was cloned again for the multiple oranges in the chocolate box.
This is another episode with multiple oranges (more than three), the others being More Annoying Orange, Million Clones, and Back to the Fruiture.
An instrumental version of Orange's theme song from Theme Song Attack! is heard playing throughout the rest of this episode.
