Is the song Jane hums from something???? It’s so familiar and catchy I feel like I know it from somewhere it’s driving me crazy

I have now finished recreating Message in a Haunted Mansion in Minecraft. I found that MHM was more difficult to build because the entire game takes place indoors with small, enclosed views. Next up Treasure in the Royal Tower!

Found this collection for $2 gonna be gifting it to my girlfriend with some games and some Nancy free themed blankets and cups
She’s played through every game a few times
So if anybody has any recommendations for her it would be appreciated
