Shrek has grown steadily tired of being a family man and celebrity among the local villagers, leading him to wish for when he felt like a “real ogre”. When he takes his family to Far Far Away to celebrate his children’s first birthday, a series of mishaps further injure his ego, causing him to lose his temper and walk out in anger.
Shrek encounters Rumpelstiltskin, who seizes his chance, having observed Shrek’s angry outburst. He follows Shrek and arranges for Shrek to appear to save his life. He gives Shrek a day to live like a real ogre, in exchange for a day from his childhood that he would not remember being erased to “thank” him.
Shrek signs the contract and appears in an alternate reality where the events starting from Fiona’s rescue are irrelevant. Now feared by villagers, he takes the opportunity to cause some lighthearted mischief until he finds “WANTED” posters for Fiona and his home deserted and desolate. He is kidnapped by witches and taken to Rumpel, now the King of Far Far Away, which has become derelict and run down.
