Can you help the insane singing creatures?

Generally speaking, I'm wary of both the holiday season and of wild animals made to sing and dance like people via the magic of special effects. That's basically what we've got in this PSA from the BBC. Snakes, lizards and insects breaking out in song, squirrels jamming on saxophones—it can't bode well for the long-term survival of the human race. That musical larva (or whatever it is) at about 0:50 is just bizarre. It's a bee larva, judging by the way it drones on.
