Grand Finale was a main character of the episode Orange of July. He explained what the Fourth of July was to Orange. He explained that he was a firework rocket, and Orange requested that he do his show. Grand Finale told him that it wasn't dark yet, and that he needed a lighter. In that case, Orange took out a lighter. Watermelon was warning him that that was dangerous, and Grand Finale told him to give the lighter to him, so Orange spat it at him, igniting his fuse. Grand Finale rocked, tipped over, and blasted into Watermelon, destroying them both. His spark went into a box of fireworks, setting off a huge firework show, in the middle of the afternoon.
"I'm Finale. Grand Finale, that is."
"No, the Fourth of July! It's when we celebrate America's freedom. And we do it by having Barbaques, parades, and shooting fireworks."
"Only the greatest party in the world!"
"No, it's not even dark yet!"
"No! Even if I want to do it, I don't have a lighter."
