With Gravity Falls currently reigning as Disney Channel’s number-one animated series in the US, the net has commissioned a second season of the mystery-comedy, and is marking the occasion with a marketing campaign at Subway restaurants.

Next month, Disney and Subway will feature Gravity Falls characters and promotional items in Fresh Fit for Kids Meals.  Each meal will include one of six reusable bags, with a specially designed Gravity Falls window decal or sticker.

Gravity Falls is currently television’s number-one animated series among kids ages two to 11, six to 11 and tweens nine to 14 in the US. A unique element of the series is its secret message sent to viewers at the end of each episode’s credits.  The key for decoding the message is incorporated in various episodes.

Disney first announced the show’s second season during its 2013-14 upfront presentation this past March.
