Gordon the Garden Gnome - Season 1 Episode 52 The Wishing Well

Jerome discovers a well in his garden and asks Gordon to take a look at it. Believing it might be a "wishing well" Gordon makes a wish and encourages all his friends to do the same. But there’s something not quite right about the well. It’s keeps asking for lettuce leaves to be dropped inside before it will grant any wishes. Gordon is suspicious that Lez and Dez, the slugs, might have something to do with it!
