为了在职业戏《愈心》中更有表现，糊咖小爱豆杨艺心申请进入壹心工作室实习，从此惹上了壹心首席心理师霍凛，发生了一系列啼笑皆非的故事，而在实习将结束之际，《愈心》因资金问题陷入停滞。谁知此时天降金主相助，等等！这金主好像是我的顶头上司！

　　The green Verdies are the tiny, but brave guardians of the lakeside. The young Verdies only become guardians when their hair turns brown. Until then, however, life is boring. The youngsters with green hair are not allowed to fly on warblers, not allowed to row alone, and they're not allowed to ride wild frogs at the rodeo. Willy Whistle's big dream is to become a guardian, but his curiosity always gets him into trouble. However, the whole lake becomes at risk when the enemies of the lakeside, the Grimps and the swans, enter into alliance. The guardians are helpless, but Willy comes up with a daring plan in order to save his home and his trapped friend, Jeremiah Jump. Luckily he is not alone, because Grandpa, the water snakes and the frogs also come to his aid.

　　概要
　　只要是有美味佳肴的地方，就一定会出现一位自称美少女天才魔导士的莉娜，和一位自称是其保护者的高里。一如往常地来到以盛产章鱼闻名的海边城市，想说只需帮忙捕鱼便可免费享用章鱼美食；却因莉娜太过於热衷捕鱼，造成不只鱼群所在处，甚至连船只都遭受破坏，最後能享受到章鱼美食的只有高里……。不过这却是整个恐怖事件的起源！一食用章鱼的人就会得到所谓「只会说章鱼话」的怪病，因而高里也被传染了。但是事件演变到没吃章鱼的人也被传染怪病，灾害持续扩大；听说高里深陷危机而前来帮忙的杰路刚帝士和阿梅莉亚也被传染，甚至连唯一的救星莉娜也无法幸免……。被封印住的魔族即将复活，人类灭亡的末日可说即将来临！莉娜她们能拯救这个世界吗？还是可以吃到美味的章鱼呢？
　　本作以TV系列的角色（高里、杰路刚帝士、阿梅莉亚和杰洛士）为主。莉娜的服装也是以TV系列为基准。另一方面，开头的BGM是继承自剧场版系列。
