Princess Pat is a scouting song and it not uncommon. See this youtube search for numerous examples:

I *believe* I remember hearing a few variants verses in the 32 recorded versions in "my" collection. It's been a while since I actively accumulated this song (most of mine were acquired in 2007).

I still have to catalog all the variants of "Baby Shark" prior to the popular version.... I *know* I have interesting variants for that song.
