Nightmare Fuel: The infamous "Pingu Dreams" episode features Pingu being stalked by a giant leopard seal which plays with him like a toy and eats the mattress from his bed as though it were a chocolate bar. This episode is second only to "Pingu's Lavatory Story" in terms of its controversy and bans.
- It's drawn level with or beaten the others in bans now. According to The Other Wiki, "Pingu Dreams" is banned in every country in the world, and probably in any alien civilizations that may have picked it up.
- Also, "Pingu Runs Away", where Pingu runs off into the night after his parents spank him for misbehaving and he imagines that he sees scary faces in the ice. This one has been banned too as much as "Dream" and "Lavatory Story", but doesn't seem to have as much exposition as either.
- Also, "Pingu at the Doctor's", where Pingu gets into an accident, hurting his nose so that it begins to bleed. Pingu in shown panicking and in pain as blood drips to the floor.
Tear Jerker: "Pingu and the Barrel Organ", where Pingu helps a poor busker. Also, when Robby's flipper is hurt in "Pingu Goes Fishing". "Pinga is Left Out" is the saddest.
