Melons blitzed in mad Czech McDonald’s ad

What in hell's name is going on in this McDonald's ad from the Czech Republic? It advertises something called the CBO, which is a McDonald's sandwich with chicken, bacon and onions. Beyond that, it's anybody's guess. From the looks of it, a cityscape is being attacked by giant seed-shedding watermelons, and the superhero-like CBO has been drafted to save the day. The onions are mad scientists who've invented some kind of new weapon, which the chicken will use in an aerial attack, with help from bacon, on the killer melons. The dialogue is hard to make out, not that that would necessarily clear things up. McDonald's hates fruit—maybe it's as simple as that. Perhaps DDB Prague can explain more.
