Oh gosh the Kids puzzles pg 56 skylanders set with the vegies is doing my head in as went back and found one I missed just then, I agree with the radishink as it seems to be one word to try trick us so heres what I found:
zucchini
carrot
potato
kale
leek
turnip
lettuce
cucumber
parsnip
beetroot
eggplant
pumpkin
brussels sprout
rocket
corn
celery
squash
So now my answer is 17, what does anyone else think?
