I was wondering if any of you has ever seen any toy robot who turns into a pumpkin.
I know the stupid Disney transformers, Jolly sheep convoy, Thomas the train, zodiac figures, numeric robots or alphabet robots, but I´d love to see a Halloween pumpkin transformer.
Any clue?

Can't say I've seen one. The only robot pumpkin I know of is from a videogame: Mega Man 7 has a miniboss in the shape of a pumpkin called Van Pookin.
