- ―Spud's original catchphrases
Spud is a living (presumably mutated) Australian-British scarecrow that wears a lavender shirt with a red and green scarf, blue trousers, a brown belt and he has a sharp cone-shaped replaceable parsnip nose which has been bent by accident twice.
Spud is a mischievous scarecrow who often causes more problems than he solves, but usually everything works out in the end. It’s Spud who needs to learn to be patient, not to eat all of the food, not to take things from other characters, etc. Spud has a habit of trying to do work and, with his limited intelligence, getting it wrong and spoiling materials. Squawk is his rival.
- In the UK dub of the earlier seasons in the Original Series from seasons 1-5, Spud's voice was more nasally and had a bit of a lisp. But in the later seasons of the Original Series from seasons 6-9, Spud's voice sounds very similar to Zippy from Rainbow. This also continues in Project: Build It and Ready, Steady, Build!
