Jerry is now a Seal
Imagine if Tom & Jerry were marine animals. Instead of being one cat, Tom is many sharks. Jerry is now a seal. About 1/3-1/2 of this is Tom and Jerry style seal abuse.
As far as learning went, there are some fun facts about marine wildlife, a lot of puns, and a lot of words written in kana when you might be more used to seeing them in kanji. Everything's pretty short and sweet though, so easy to consume.
