Rico is the explosives-loving penguin from the Madagascar franchise, led by Skipper, and the running joke is that Rico can produce almost anything, especially explosives, from his stomach. The Penguins of Madagascar spin-off turned that gag into a catchphrase-style shorthand for blowing something up on cue. Clips like this spread through short-form video and soundboards because the setup is instantly recognisable even without the full scene, and the single word kaboom works as a punchline on its own. It remains popular for edits where a small decision leads to absurdly large consequences.
