Looking for a comic I have a vague description of

[Jallorn]

My friend told me about a comic he read once that he doens't know the name of. In it he remembers two stories about the same silent protagonist. In one the protagonist saves children from a demon school bus, and in the other he saves the world from an alien "judge" robot with the children's toy where you pull the string and it spins and says, "The [animal] goes [sound]."

Any clues?
