《睡衣英雄》（Pajama Hero Nemo / パジャマヒーロー NEMO）由 Capcom 開發，於 1990 年 12 月 7 日在任天堂 Famicom（紅白機）上推出，是改編自經典動畫電影《小尼莫》的動作遊戲傑作。誕生於 Capcom 製作紅白機遊戲的黃金年代，以夢幻的畫風和獨特的「動物附身」系統，在玩家心中留下深刻印象，被譽為紅白機上最優秀的漫改動作遊戲之一。

視覺設計色彩繽紛，充滿奇幻感，場景從繁星點點的森林、玩具王國，到陰森的噩夢之地，細節精緻而豐富。音樂和音效由 Capcom 的招牌音樂家製作，旋律既帶有童話般的純真，又蘊含冒險緊張感，音質清脆悅耳。操作手感延續《洛克人》系列的精準判定，主角尼莫的動作雖簡單，但透過「動物附身系統」延展無限可能，使玩家能在關卡中運用策略與技巧完成挑戰。

故事劇情改編自溫瑟·麥凱的漫畫原作，講述少年尼莫在夢中受到夢之國公主的邀請，前往夢境擔任她的玩伴。然而美好的夢境正受到「噩夢王」的侵擾，尼莫必須穿上睡衣，帶著能與動物溝通的魔法糖果，穿越八個夢境關卡，最終取得王室的晨星之杖，闖入噩夢之地擊敗噩夢王，恢復大家的美好夢境。

核心玩法不是直接戰鬥，而是「收服動物」。將糖果投擲給特定動物，當牠們吃下三顆糖果後會陷入昏睡，便可進入其身體，獲得動物的特殊能力。青蛙擅長高跳和游泳，鼴鼠能挖掘地道，大猩猩力量強大，可以攀爬牆壁並出拳攻擊，蜜蜂可在空中飛行並發射針刺，螃蟹則能在沙地挖掘並剪斷障礙物。每個關卡的目標是收集散落在地圖各處的鑰匙，集齊後才能打開通往下一個夢境的大門。

在市場上獲得高度評價，不僅因為其系統創意十足，還因關卡設計巧妙。雖然畫面看起來童話可愛，但後期關卡難度頗高，需要靈活運用動物能力來克服複雜地形，充分考驗邏輯與反應力。由於遊戲需要尋找鑰匙，探索元素也相當豐富，這在當時以單線路為主的動作遊戲中非常罕見。作為 Capcom 在紅白機末期「精品化策略」的代表作，《睡衣英雄》的完成度在核心玩家心中堪稱頂尖，雖然知名度可能不如《洛克人》或《快打旋風》，卻同樣令人印象深刻。

這款遊戲最經典的回憶，莫過於為了跳上高聳的懸崖，拼命追著青蛙跑並餵牠吃糖果的趣味過程，或者在「噩夢之地」關卡首次拿到威力強大的晨星之杖時的那種感動與成就感。

Pajama Hero Nemo (Pajama Hero Nemo / パジャマヒーロー NEMO), developed by Capcom and released on December 7, 1990, for the Nintendo Famicom, is an action game adapted from the classic animated film Little Nemo: Adventures in Slumberland. Emerging during Capcom’s golden era of Famicom development, the game left a lasting impression on players with its dreamlike visuals and unique “animal possession” system, earning a reputation as one of the highest-quality anime-based action games on the platform.

The game’s visuals are vibrant and fantastical, with meticulously detailed environments ranging from starry forests and toy kingdoms to eerie nightmare realms. Its music and sound design, composed by Capcom’s signature musicians, balances fairy-tale innocence with a sense of adventurous tension, all rendered in crisp, clear audio. Player control is precise, reminiscent of the Mega Man series, and while Nemo’s basic moves are simple, the “animal possession” system adds a layer of strategic depth, allowing players to creatively approach each stage.

The story is adapted from Winsor McCay’s original comic. Young Nemo is invited by the princess of Slumberland to become her playmate. However, the once-idyllic dream world is under threat from the Nightmare King. Nemo must don his pajamas and wield magical candy that allows him to communicate with animals, navigating through eight dream levels to ultimately acquire the royal Morning Star and defeat the Nightmare King, restoring peaceful dreams to the realm.

Gameplay revolves around capturing animals rather than direct combat. Nemo can throw candy to specific animals, and after consuming three pieces, the animal falls asleep, allowing Nemo to inhabit its body and gain unique abilities. Frogs excel at jumping and swimming, moles can dig tunnels, gorillas possess great strength to climb walls and attack, bees can fly and shoot stingers, and crabs can dig through sand and cut obstacles. Each level’s goal is to collect keys scattered throughout the map to unlock the door to the next dream world.

Pajama Hero Nemo received critical acclaim for its inventive systems and clever stage design. Despite its cute, fairy-tale aesthetic, the later levels present a high level of difficulty, requiring players to switch between animal abilities strategically to navigate complex terrain, testing both logic and reflexes. The game also incorporates exploration elements through key collection, a rarity for the predominantly linear action games of its time. As one of Capcom’s hallmark “premium” titles in the Famicom’s later years, it remains a standout in terms of design quality, even if it is less widely known than Mega Man or Street Fighter.

One of the most memorable experiences in the game is chasing a frog across a towering cliff while feeding it candy, or the exhilaration of obtaining the powerful Morning Star for the first time in the Nightmare Realm, a moment that perfectly captures the joy and challenge of the game.
