You could try getting a zebra-print bedspread, or some zebra throw pillows for your room. I do agree that the bright colors, while fun for a while, can become exhausting.
You should be able to locate a few wildlife pictures even taht feature zebras.
Good luck!How can I change my room without changing my wallpaper?
Try a different combination of colors to pair with your wallpaper.
Make sure it includes yellow and pink in small amounts so the walls
and Accessories will still coordinate. A zebra rug with yellow or pink in it would look good.How can I change my room without changing my wallpaper?
I wish that you had told us if the wall paper had a pattern in it or not.
but from what you did say I will think of it as yellow wallpaper with a pink boarder.
Here are some links to some possible ideas you might consider as choices.
I am thinking that if I were you I would try not to add more colors to the room than you have unless it is black or white.
Here is a black pink and white bedding set. it would go very well. Then you could toss some yellow pillows to match your walls.
You do not need to add a lot of yellow to the room because the walls are already yellow. That is adding a lot of yellow to the room already.
Maybe add a picture to the room that has the same colors with a touch of yellow in it.

Add some pink sheets to the black and white zebra print would go well. Toss some yellow and and pink pillows with a matching pink and yellow rug would look great!

Use some black framed prints with some zebras on your walls to tie it all together. As well as some black accents perhaps a black lamp on your night stand or desk.
If you can, paint your furniture white,
Best wishes have fun and make the room with your personality in mind.
