Far East Babies(ファー・イースト・ベイビーズ)

Wakute becomes inconsolable when a dastardly fiend swipes his obaasan. It turns out that this obaasan is in fact a bizarre, carved fetish object of mysterious ethnic origins. While searching for the item digging holes at the beach, he and his mates have a mystical vision of an amateur ethnographer, living on a deserted beach, in possession of the object. Soon they head off for this mysterious island, ukuleles and guns in tow.
