- "Wowie-wow! Another sunshiny, funshiny day!"
- — The Sun
The Sun is a hot-air balloon controlled by Princess Sunshine. It also functions as an actual sun, making its way across the skies of Dreamside each day. It has a sunny attitude and a peculiar way of speaking, utilizing rhymy-whymy nonsense words and overusing terms like "gosh" and "golly."
