Create a cartoon kangaroo character standing upright, with a softer pastel color palette instead of the original brown tones. Instead of holding an ice cream cone, have it holding a colorful, multi-layered slice of cake. The background should be a minimalistic, light-colored setting to keep the focus on the character. Additionally, give the kangaroo larger, more expressive eyes for a friendlier appearance and adjust the ear shape to be more rounded.
