Breakout Character: In the original story, he was a nameless cricket who was squashed by the title character early on and appeared later as a ghost. In the Disney version, he was given the name Jiminy Cricket and promoted to narrator.
Even Evil Has Standards: He's perfectly fine with conning small children out of their money and freedom, and if one scene is to be believed, with doing hits as well. However, when the Coachman mentions taking young boys to Pleasure Island, he's absolutely horrified. And when the Coachman assures them that the boys won't return as themselves and makes a Nightmare Face for emphasis, the fox cowers in fear.
Greedy Jew: Despite being Italian, seems to be the model of this.Actually... The Greedy Jew stereotype first appeared in Italy, as it was the banking center (and therefore usury center) of Europe for the Middle Ages and early Renaissance. This can be seen in Shakespeare's Merchant of Venice.
Sudden Name Change: Was actually referred as "Barker" in the film's subtitles when he finally brings several boys which he kidnapped (including Pinocchio himself) to Pleasure Island. However, the subtitles start to refer him as "Coachman" again when he and some gorilla-demon-looking-things start to round the now-transformed boys into crates headed for either the salt mines or the circus.
They Look Just Like Everyone Else: Part of what makes this character so terrifying by Disney villain standards is that he basically looks like a normal, grandfatherly old man. There's no clear visual indication of his evil until he makes his Nightmare Face.
Jerk with a Heart of Gold: He's a troublemaker and that's exactly what got him into this mess. But deep down he loves his mother, so his transformation into a donkey isn't complete, and unlike Lampwick and the majority of the bad boys on Pleasure Island, can still talk.
Informed Species: Monstro doesn't look like any real species of whale. The closest possible match, Livyatan Melvillei is nowhere near the same category of scale. He has the underbelly of a blue whale. From the side he looks a bit like a sperm whale, but a sperm whale's jaw is narrow, unlike Monstro's shovel-jaw.
It Can Think: Pretending to be asleep in order to catch the school of tuna, while grinning evilly to himself. Trying to intercept Pinocchio and Geppetto's escape course during the chase and smashing up their raft to slow them down.
