This is what looks to be a development sample of the fat Jake plush made by Jazwares for the Adventure time toy line. Plush uses a internal Sample hang tag that has writing on it from a Jazwares Employee Presumably. Plush also uses a Released tag as well as its normal tush tag so this looks to be very far in development before it went into mass production. Plushies build is also very similar to the released counterpart although looks to be a bit higher quality. Please see photos for best details.
