Watermelon appeared in Annoying Orange: Orange of July as the main antagonist.
He was being annoyed by Orange about a party on the 4th of July. In the end, Orange spit a lighter at Grand Finale, making him go flying and hit Watermelon, killing him. The fireworks in the box started popping, to which Orange said, "What a bunch of 'popheads'!", followed by his signature laughter. The camera then zoomed out, revealing some fire burning next to Orange (it's possibly because when Grand Finale hit Watermelon, they both exploded).
Watermelon was voiced by guest star Lukeboedi.
- During the conversation between Orange and Grand Finale, Watermelon didn't say that much lines.
