This one takes place during the Dice Island arc (The Thimble Theater arc Popeye debuted in). Having won all of the money in Fadewell's casino, Castor Oyl gives half his winnings to the collection of now-broke ex-millionaires gathered on the beach so they can get home.
After 70 years of being a father figure, Popeye officially adopted Swee'pea in a Sunday strip from November 21, 2004 in celebration of National Adoption Month. This was also marked by a special event held in New York City.
In the Plunder Island story arc, Popeye is fighting Alice the Goon when a little goon runs up and shouts "Mama!" Popeye is blown away to learn that Alice has a kid. He immediately stops the fight and promises to free Alice from the Sea Witch, so the two can go back to their home.
In "Leave Well Enough Alone", while Popeye really should have thought through the idea of buying all the animals in Olive's pet shop and letting them loose on the street, that he was willing to part with 500$ for their freedom really says a lot about his generosity (and keep in mind, 500$ was an even bigger amount of money then than it is now). At least he had enough sense to round them all back up to Olive's shop once things went south (and parted with even more of his money just so the animals he unwittingly freed wouldn't wind up in the Pound).
In "Cops is Always Right", Popeye, despite being annoyed by the bookish police officer, is so good hearted, that when he accidentally knocks the officer out with a flower pot, he's horrified—he proceeds to drive himself to the police station, deliver the unconscious officer there, and then lock himself up in a cell!
Early in the film we see Popeye keeps a picture frame with the words Me Poppa in place of a picture. The CMOH comes later when we see Pappy has an identical picture frame with the words Me Son.

During the Sail With Me/Stay With Me song, Olive and Popeye sing about the futures they hope Swee'pea will have. There's a part where Olive is singing about how Popeye might be the guy she's been dreaming of, and that she hopes that he'll settle down with her.
There's also "He Needs Me", where Olive sings about how Popeye is the first person who's ever needed her.
