Identifying literary devices

Hello,

I need help analysing literary devices. Maybe you could give me any ideas?

I’m analysing the film “Mr. Peabody & Sherman” (2014) and I need to find literary devices in it. I’m not a native speaker. In the following examples I’m giving my guesses:

• …of perhaps the most unlikely genius the world has ever known. (Is the phrase in bold metonymy/hyperbole/personification or neither of them?)
• Let’s just say, the Leaning Tower of Pisa wasn’t always leaning. (Could this be a pun? Or maybe epanalepsis?)
• I’ll stay, I’ll heel, I’ll even shake hands. (Is this anaphora/parallelism or isocolon?)
• If a boy can adopt a dog, I see no reason why a dog cannot adopt a boy. (Antimetabole or chiasmus?)
• I think we can file this night under “Unqualified Success.” (Could this be a metaphor?)
• Spoiler alert, King Tut dies young. (Could this be any kind of literary device?)
• Old “Flip-Flop Ra,” we call him here in the underworld. (What about this flip-flop Ra?)
• – Because I’m sitting here all day on my abbondanza! – I don’t think that means “chair” in Italian. (Could this insertion of a foreign word be any kind of literary device? I’m guessing it was done for a reason…)
• Are you ready to get on the field, Shermanus? (Also this one. The real name is Sherman.)
• You may kiss the Grunion. (Also this modification of “You may kiss the bride”).

Any kind of help would be welcome!
