Overview: Percy wins a competition and heads off for a day out at Gadget Heaven Theme Park - but not before he's instructed Gordon in the finer point of his garden maintenance schedule. Unfortunately, the Chief Gnome has other plans for Percy's garden and insists that Gordon supervise the trainee Ian Gnome in looking after the garden to further his education. Predictably, Ian's talent doesn't live up to Percy's rigorous standards and Gordon has to solve numerous gardening disasters. Can Gordon get the garden back into perfect condition before Percy returns that evening?
