Yuck Éclair is a gooey, dirty éclair. His mouth is formed between the two halves of dough, with mushy filling dripping around and below it. His top half is drizzled with runny frosting, with his half-closed eyes nestled on it.
- Yuck Éclair is similar to Creamy Bun Bun, a Season 1 Shopkin.
- He is the only Grossery to have an accented letter in his name.
- His static art colors him dark brown with a white filling, a color combination that his figures are not available in.
