Perth 'Spud King' Tony Galati stayed true to his word on Tuesday and paid his pint-sized clone Joshua Gonzales a visit at his school, leaving a sizeable donation.

Joshua, 9, from East Fremantle, drew Galati's attention after dressing up as the Spud King himself for book week and writing his autobiography.

Joshua's mum, a mother-of-four, said her kids had always liked the Spud Shed ads on TV and all of them could recite his catch-phrase 'what, no potatoes?'.

"All my kids love the ads on TV and I think with my Italian heritage they just love having a laugh... my dad thought it was hilarious," Ari Gonzalez said.
