Is Baby Shark hypnotic?

I seem to remember BabyShark was the song that Jess Phillips got children to sing outside Downing Street. I can't remember why now. It is mildly irritating but then I'm not 5 .

Old MacDonald for my darling grandson.

My 22 month old granddaughter would listen to Baby Shark all day if permitted, whereas my three year old grandson loves a French nursery rhyme about a crocodile and can sing it beautifully (his mother is French).

Only yesterday, dil sent me a video of dgd (2) singing herself to sleep with that song, and with a caption saying it is by far her favourite song at the moment.

Baby Shark ? and Peppa Pig ? are currently the soundtracks of my days.........the joys of being a grandparent ?

‘You can’t get friendly with a crocodile’? I used to sing that to my GS!

Not exactly hypnotic but very difficult to stop hearing in your head. I think they call it an ear worm.’ Never smile at a crocodile ‘ is another one for me. But I can never remember the second line. Oh no. It’s started me off again
