The cartoon Larva can be viewed silent, in fact until I watched it here on YouTube I had never heard it because the bus does not have sound on for the BusTV. Larva does not need the sound to be fully enjoyed. They are just short stories about two little Larva (caterpillars or something) that live in a drain and their various other acquaintances and or the things that they find washed into their drain. Each episode is about two minutes long and they are often pretty macabre.
It’s cute, funny and mildly diverting on my daily bus ride to work
