Spud's on the job!" and "Oh, yes, yes, yessity yes!
— Spud's Catchphrases
Spud is a naughty scarecrow who lives on Farmer Pickles' farm and always attempts to help Bob and the crew, although his efforts usually end in disaster.
Spud is a living (presumably mutated) Australian 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.
