Following the haunting "Finn the Human" episode of Adventure Time, many fans may have thought they'd never see the bleak "Farmland" timeline again. Leave it to Ryan North, Shelli Paroline and Braden Lamb to not leave you hanging, though. A comparatively dour version of AT's last boy on Earth known as Finn Mertens a.k.a. "Farmland Finn" returned in the last issue of AT and his mechanical-armed adventures continue in  Adventure Time #19 on August 21. Things aren't exactly what they seem this time around, however, as both Finn and his best friend Jake the dog work together to overcome the weirdness of converging nightmare worlds.
