Some dogs are mentioned to have been killed off-screen, before the events of the story. Later in the comic, a dog's bloody corpse after being murdered is actually shown.
Bugs says that he dresses up as a girl and kisses trolls to prevent them from trolling him, similar to how he does in the original Looney Tunes cartoons, though this isn't actually shown.
A character throws their feces as an attack. The defecation is shown on screen. Another character’s attack is assumed to be a “Golden Shower” by their enemies before the effects set in.
Tails Gets Trolled is a comic, so any events that could cause misophonia ( One character can use abilities by saying certain words, another has a shout attack) likely wouldn’t affect the reader unless they are experiencing the story via a comic dub.
