These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
Squick: In one episode, one of the two eats uncooked meat and gets a tapeworm. The other one goes to see, and it jumps into his mouth. (A puppet tapeworm, but still.)
Uncanny Valley: Almost every character. Even the non-human puppets come off as creepy. But none are as nightmarish as Chip 2.6, a robot assigned to work at the Mr. Meaty at Scaunchboro Mall in the episode "Model Employee"
