What is this on my iPhone?

What is this on my iPhone?

Hey everyone! I have no idea what this is and if someone can help me out, I’d really appreciate it.

So I was looking through my cellular data and all the way at the bottom I find this, something called Boo. I have no idea what it is. I’ve looked through my apps but I can’t find it. I’ve looked at hidden purchases and there wasn’t anything. I’ve checked to see where my Apple is signed in or if I’m sharing anything with anyone but zilch. It seems like the only place I find it is where my cellular data info is at.

As you can see it’s pretty ominous and I’m pretty much freaking out thinking it’s some of virus or something.

Thanks in advance for the help!
