Best of luck with exams!

As long as it's pixpet related :) nothing lewd. PG, VERY PG.

Yes related to all kinds, that's why we mentioned friendship a well. In that sense a wallpaper with rainbow hearts for example would work. Or even a comfortable looking set of food to represent pixpets sharing a meal over friendship, that kind of thing. A picnic set, a fishing set etc things you might do with your friends can also be used as inspiration. I imagine colour choice will play a strong role.

At the end of the day the theme is an inspiration and please keep in mind that whatever is designed should fit into the pixworld.
Have fun :D
