13th Birthday Party!!! Help Needed And Ideas Given

Hi, i need some ideas for a 13th birthday party! But to make this deal fair, here are a few ideas for other age birthday parties:

1) : A younger childs party: a beach theme. Sand castle cake, flipflop gift bags, sunglass invitations, water vollyball games, and more.

2) An older teen`s party: a murder mystery party theme. Everyone comes dressed dead, bloody bones food (ketchup and chicken wings) and a live clue game right in your home!

I hope you enjoy those themes for birthday parties for older and younger than 13th birthday party!!!!
In return I would appreciate it if you would give me some ideas for a 13th birthday party for my daughter!
To give any suggestions, please reply to this message, thanks and have a nice day!
