Lili and Leo were still arguing — they didn't even notice the world had changed, until Mum and Dad pointed around them.
"Wait," said Lili, looking up. "This is the video game I was just playing!"
And then their clothes began to change — and so did something deeper inside them. Each of them had a power.
Dad stamped his foot and the ground rumbled — he had Earth power, and his tie became a cape, his coffee mug glowing.
Mum lifted her hand and the air swirled — she had Wind power, with a golden battle-cloak and a frying-pan shield.
Leo clenched his fists and sparks crackled — he had Fire power, in blocky diamond-blue armour with a pickaxe that could break anything.
But Lili? Lili got her glowing silver armour and her stylus-sword... and when she tried to feel her power — nothing happened. She felt scared. "Why don't I have a power?" she whispered.
Even the pets had been pulled in! Pip the hedgehog could now curl into a super-fast spiky speed-ball, and Blaze the parrot burst into bright flame-coloured feathers that lit up the dark and shot little sparks.
Suddenly an army of tall, crispy French Fry Guards came marching, each holding a little ketchup-blaster. "By order of the Great Potato — surrender and play forever!" they shouted.
Lili looked at Leo. Leo looked at Lili. They were still a little mad... but they both knew what they had to do.
"Truce?" said Leo.
"Truce," said Lili. "Let's mash some fries."
