The candy shopkeeper is a minor character in Yu-Gi-Oh! ZEXAL.
He was briefly shown trying to sell various customers his stock, but Flip decided to lie to cause mischief, telling the people buying the candy that it was out of date, which caused them to leave it. Angered by this, the candy store owner challenged Flip to a Duel, which he lost. Flip then claimed some of the man's candy as his prize before leaving.
The only card from his Deck that was shown is "Grenosaurus".
