Wow, that took a lot of time and effort to record all these BabyCharm, good job.
Personally, the first term I thought of when hearing the title "Infernal Slumber" was "infernal summer", meaning a hot "hellish" summer. I've both heard and said it a number of times throughout my life. So the pun for that title might be interchangeable. Although the term "eternal slumber" does make more sense when compared to the actual episode.
And as for "All Zapped Up", I quickly think of the term "all hyped up", meaning extremely hyper and excited. And that would make sense for the short since that's exactly what Bloo is in it- all excited about all his new found "power" of static electricity.
