每年，Bunny 都會開著露營車，到一個安靜的地方度假。她喜歡獨自聽風聲、看星星，享受屬於自己的平靜時光。
今年，她找到了一個完美的營地，正準備好好放鬆，卻在隔天早上發現——隔壁多了一頂紫色帳篷，還住著一隻吵吵鬧鬧的紫色怪獸。Bunny 心想：「我的假期完了！」
幾天後，一場暴風雨吹走了怪獸的帳篷。Bunny 原本鬆了口氣，但看到他淋得全身濕透、孤零零地站在雨中，她忍不住打開露營車的門，邀請他進來避雨。
從那天起，他們一起煮飯、看星星、到森林探險。Bunny 發現，雖然安靜很美好，但有人分享的笑聲，會讓假期更快樂。
當假期結束時，Bunny 已經開始期待明年——因為這次，她有了新的旅伴。
Bunny's plans for a perfect holiday are wrecked by an unwelcome surprise holidaymaker who changes her life in a most colourful way.
As every year, Bunny looks forward to parking her camper van in a peaceful spot, and enjoying her usual routine of relaxing amongst nature – on her own. To her horror, she wakes up to find a noisy purple monster camped right next door! At first she is delighted when a storm blows away his tent, but then she can’t help but take pity on his plight, and gradually realises that doing things together can be more fun than solitude.
