I have the ice cream lamp, but in different variations. You can customize it in different colors (chocolate swirl, green tea, etc). I have four of them in a line on the far side of the room and it looks cute.
A few shaved ice lamps would look really good, as well as things like cake, candy, chocolate fountains, dessert case etc. if you don't have them already. It depends what your room looks like currently but some darker brown furnature might look good and balance the colours a bit (I forget the name of the set, but there's one with brown bookshelves and things) maybe some rococo too, maybe a violet screen or 2? Plants look good added in almost any room too, there might be a few nice plants that fit your room
