Adventures On A Deserted Island

Ok, like the title, it’s very simple.
 
You are now on a deserted island and like many stories, there’s a jungle, beach, and adventure!  
Probably romance as well.
 
You start with either one of these 3 objects.
 
1)Box of matches  
2)Pocket knife  
3)Toilet paper
 
Let’s go surviving!

Also, I’ll be watching you guys like a monologue.
 
:D

a tan mare with a dark red mane pops out from a tree. She’s got both wings and a horn. Oh dear. Where’ve I teleported myself now?
