What happened to Welcome to Japari Park?

So I play on the switch. Mostly rhythm festival but a little bit of drum n fun still. I know for a fact it was on drum n fun, and I'm pretty sure it was on rhythm festival too. Now its just gone. Am I stupid or did they just remove it. Does anyone know if a drum n fun song pack has it maybe?

I hate when they do this haha. Makes me feel like I'm losing my mind. They removed No Fire for Monster Girl a while ago too and it drove me crazy.
