New scarf? Card

I’m so confused!!! I see this new card on the right of my stacked cards. I believe I read somewhere that it is called the scary card. But I’ve tried everything to use it even though I don’t understand the purpose and nothing I’ve tried worked. Does anyone know how to use it and what exactly it does? I’d appreciate any info you may have!!! Thank you! Jenn

Can you please provide a screenshot of what you’re talking about? Also, on which island below are you referring to?


Sounds like the boomerang…
